Subject: inifinte duration defined in a list attribute?
Message-ID: <WED.4.JAN.2006.112256.0500.ST704@NYU.EDU>

Hi all,

I'm hoping to set up an experiment in which the same slide event varies 
between a timed and infinite duration but I'm having trouble getting 
the event to accept "infinite" or "(infinite)" as acceptable durations 
specified in a list.  

I realize I could put a long duration value into the list in the hopes 
that subjects don't wait too long during the event, but if possible I'd 
like to specify a genuinely infinite duration.

Thanks for you help,

hi shannon,

just use the value -1 for 'infinite' duration

Dear Leisha,
If I remember correctly, there were some issues with refresh rates of laptops so
that timing may not be as accurate as you want.  This may be neglibile for
decision research.  You may want to have a regular CRT to plug into.  I think
some of this is addressed in the list serve archive.

Leisha,

I have been playing with several older IBM Thinkpad Laptops -- these are
some of the finest PCs available, although they are rather pricey when
brand new. They are rugged, reliable machines that won't let you down. I
have not tried to put E-Prime on these machines, but I might try that in
the future. The Thinkpad would be my first choice as a portable platform
for experiments. They are also highly modular, and easy to modify (
CPUs, batteries, memory, drives ) I will be happy to give you basic
information about the various types of Thinkpads out there and discuss
this further, if you want to email me off list.

We ran RT experiments with EPrime on Toshiba Satellite Pro laptops, because 
that was what was already being used in the larger study that we're a part 
of.  My testing showed no crucial timing problems, and the examiners in the 
field have not complained of problems running our programs.
Maybe I should add that the stimuli were entirely auditory, so screen 
refresh rate, etc, was not an issue.  Also, we used the response box.

Hi, Dr. Wright,

For you and for the list, here is a synopsis of the replies I've 
received to my laptop queries so far. I've received recommendations for

1. Toshiba Satellite Pros, on which Carol A. Miller actually ran RT 
experiments with eprime.

2. Dell Inspiron
    + Dell again, with the caveat to use the AC power rather than the 
battery, to avoid timing issues. Thank you, Mr. Bigio.
    + Dell Inspiron, recommended by Kim Lesniewicz. However, her Dell 
has a wide screen that stretches text, and we wish to avoid this. Also, 
she has found it necessary to reboot her laptop after each run to solve 
a freeze-up issue, and I don't wish to ask our experimenters to do this.
    + Lee Hogarth recommends a Dell Latitude D505, saying it has never 
failed her. Actually the Dell Latitude D610 meets our present 
specifications, but I think I can do better on price.

3. IBM. Highly recommended. I agree with Dr. Sudevan that they are 
rugged & reliable, but he has not used them specifically with eprime.

4. General issues. Dr. Crowley reminded me to check the archives for a 
discussion of timing issues on laptop computers, including refresh rates 
and use of AC power versus battery.

5. A final issue to add: We use input devices that were made for our RT 
experiments. They are large switches or buttons, one for each hand, that 
can be pushed easily and give a solid clicking sound. They are wired 
into a serial device because when we began this series of RT computer 
experiments, we were told that the serial port was the cleanest, 
quickest way to get to the processor and we are measuring very fine time 
differences. Now serial ports are hard to come by on laptops, and when I 
read about new laptop connectors I find that the now-standard FireWire 
IEEE 1394 is a port that was designed for using a computer in "real 
time," that is, to play 3D games or to interact with streaming video. 
Wouldn't this now be the best port for measuring very fine time 
differences? Or is serial still the best way to go?

I'll post another synopsis of replies received.

Thanks for all your help.

Thanks. I'm looking at 2 gigs of memory for each laptop. I'm loading 
multiple images per slide, too. But I can load the background first, 
pause, then load the actual stimulus. This should help me control 
refresh time, but how do I measure it to be sure?

This does help. The experiments we are running are actually very simple, 
and I will review the critical timing information for eprime to be sure 
I understand your method.

hello Leisha,

A small note on ‘real time’ issues:

Since marketing people like to use ‘sexy’ words to promote additional 
functionality or suggest superior specifications, we have to be a bit 
careful how to interpret the words ‘real time’ correctly. The actual meaning 
depends on the context: Most hardware and software engineers use the words 
‘real time’ to indicate that the time allowed to execute some kind of 
operation is limited to a known maximum. Some engineers also differentiate 
between so called hard and soft real time. In hard real time systems it is 
an absolute system failure if the real time criteria are not met. (Ie. the 
air bag in a car is definitely a hard real time system.) In soft real time 
systems the real time criteria are less strict. This is the case with EPrime 
where it is sufficient to keep track of such timing failures. (See also 
http://en.wikipedia.org/wiki/Real_time) Anyway, this kind of real time is 
about the response time limits of a system, not its execution speed or 
bandwidth.

Real time streaming media protocols on the other hand, are said to play 
media in ‘real time’ when it is possible to play the media stream at the 
correct speed (ie. not in slow motion.) So, in this case marketing people 
and engineers refer to the large bandwidth or execution speed of the system, 
not maximum response latency. In other words: even though Firewire and USB 
standards support large bandwidths, this does not mean that they support 
short (<1ms) transmission delays. Furthermore, the complex protocol stacks 
that are used to implement those communication systems make it almost 
impossible to realize short latencies. But even if you are willing to accept 
timing errors, it is not very trivial to develop hardware that connects 
through USB or Firewire. RS232 and parallel ports are much easier to use in 
both hard- and software.

There are some real time systems that use another common connection between 
de external hardware and the computer: Ethernet. A (dedicated) Ethernet 
connection supports high bandwidth and short transmission latencies. 
However, as with USB and Firewire, it is not very easy to develop hard- and 
software for such a connection. (Note that PST writes it will support some 
kind of Network Socket Device in version 2.)

So your advice is to stick with the serial port? Thanks for the

Hi Leisha,

The serial port is fine. Although in most cases the parallel printer port 
and the game port are also usable. This is the case when the buttons are 
connected 'directly' to the input lines of the port (not the serial Rx/Tx 
transmission lines) and a 'Port' device is used in EPrime to scan the 
corresponding IO register. (See also 
http://www.psy.vu.nl/download/menu/index.html)

Note that the PST Serial Response Box uses a different technique to send the 
button states to the serial port. In this case a sequence of bytes is 
transferred to the Rx line of the serial port. It is not very likely that 
your button box uses this serial protocol because it requires additional 
electronics and software.

best,
paul

Thank you, Paul. I checked out the link you sent me. My serial device is 
not a box at all--it's two buttons designed for people who have physical 
limitations. They are about 2-1/2" in diameter and very easy to press, 
resulting in a clear audible click. There's no box at all: the buttons 
are wired into a serial connector that I bought at Radio Shack. The 
buttons are configured as a port device where the left button returns a 
5 and the right button returns a 6.

Does this sound similar to how the PST Serial Response Box works?

Your advice has been extremely helpful. I will be able to answer all the 
technical questions that are thrown at me about this purchase when the 
time comes & make my recommendation with more confidence, thanks to you.

Sincerely,

Leisha

Supposedly this is something coming up in Version 2. But that doesn't

But haven't people suggested a couple of ways to display video as part 
of an E-prime script in the past? I mean, suspending E-prime & calling 
out other executable files, chaining a bunch of bitmaps together to 
create a video effect, or creating some kind of dual-monitor display?

 As far as I'm aware, E-prime doesn't handle multi-byte fonts (e.g.
Japanese) very well.

When constructing a script in japanese, I use Word and Arial Unicode to make

free alternative) to grab screenshots, and use picture stimuli instead of
text stimuli.  This is the same technique I used with Psyscope - 1.2.2 under

A bit of a hassle, but it works well here (and as here is Linguistics rather

Hi,
I'm a Japanese student using E-prime, I know a tip to display Japanse
fonts with a TextDisplay object.
My suggestion is to implement text stimuli directly in the EBS file.

Your .ebs file should have a line to 'InitTextDisplayDefaults' as below:

theTextDisplay.FontName = "..."

Change the font name ("...") into the one which can handle Japanese
characters.

Then you can write in Japanese the content of each TextDisplay object,
e.g.;
TextDisplay1.Text = "...(in Japanese)..."

That's it. 
Now you can run the script.
Does it work?

Hiro 

# Still, it's a lot of work when you have a large number of item to
  display. I think most Japanese users don't take this way, instead
  use the  ImageDisplay to present Japanese words, as Eddie discribed.

Subject: problem with summation object
Message-ID: <FRI.20.JAN.2006.121332.1100.HESTERR@UNIMELB.EDU.AU>

To the mailing list,

I have been successfully using the summation object script (available on 
the e-prime website) to collect and average the number of correct responses 
from 100 trials, but I've run into a problem when I changed the stimulus 
timing properties of the task.
I've have a flanker task setup so that the stimulus display object is 
presented for 100ms and then changes to a second stimulus display object (a 
blank screen) while it waits for the participants response. I have the 
stimulus display object 1 response properties configured so that it runs 
for 100ms (cumulative timing with 100ms) with the response input time limit 
set to 'infinite' and end action set to 'terminate'. Stimulus display 
object 2 does not accept responses, but is set to an infinite time limit. 
The summation object in line script is placed after Stimulus display object 
2 (although it doesn't matter if I move it to after SDO1), and reads:

'The AddObservation command adds the ACC value of object
'StimulusPresentation to the Summation object, OverallAcc.
OverallAcc.AddObservation c.GetAttrib ("stimulus.ACC")

'The Debug.Print command prints the mean value of the Summation
'object, OverallAcc, in the Output window.
Debug.Print OverallAcc.Mean

'The OverallACC attribute adds the running calculation of overall
'accuracy to the data file at the trial level.
c.SetAttrib "OverallAcc", OverallAcc.Mean


How does having the second display object interfere with this script, 
because removing makes the summation work perfectly? Anyone got a suggestion?

Cheers
Rob

Hello Rob,

I don't think the problem relates to the summation object itself. In some 
cases the values of attributes are not set properly during the script. 
Instead, you could use the parameters of the corresponding EBasic objects 
directly. It is in some cases also required to manually terminate an 
infinite response. Just try the following:

If stimulus.InputMasks.IsPending Then stimulus.Terminate
OverallAcc.AddObservation stimulus.ACC

To validate this, you could add some test code before the two lines above:

Debug.Print "---- "
Debug.Print "pending: " & stimulus.InputMasks.IsPending
Debug.Print "acc:       " & stimulus.ACC
Debug.Print "acc$:     " & c.stimulus("stimulus.ACC")


Cheers,
Paul

Subject: Slide simultaneously displaying 2 stimuli from 2 independant lists
Message-ID: <TUE.24.JAN.2006.105406.0100.CDEVUE@ULG.AC.BE>

Dear E-prime users,

I'm trying to display a slide composed on each trial of a different face 
and of a pair of different numbers.
The faces have to be different in each trial and randomly appear on the 
right (half of them) or on the left (the other half). These faces have 
to appear in a particular sequential order. Regarding the numbers, there 
are 4 kinds of pairs and they have to appear in a random order.
The subject's task is to respond to numbers while ignoring the face.

Thus, the point is that one face and one pair of numbers have to appear 
on the screen AT THE SAME TIME (and same duration).
To do so, I have tried to make a list, let's say 'DisplaySlide List', 
with 2 Nested lines, to obtain a sublist for faces and another for numbers.
Then, I insert a Slide in the TrialProc (defined in the DisplaySlide 
list, and I've even tried it with a higher order additional list) 
appealing a face AND a pair of numbers from the two sublists. But it 
does not work.
When I try to run the experiment, I obtain an error message (saying that 
it cannot find one column refering to either a face or a number). 
Nevertheless, I know that there is no problem with each idenpendant 
sublist (because a made 2 scripts with each one in order to check, and 
each of them work as i want).

As I can understand, Nested Lists make the different items within the 
different lists appear sequentialy. So I think, this is not the good way 
to make the face and the numbers appear at the same time. But i do not 
know the right way to do it.
However, I think I had to make these two different lists for faces and 
for numbers because they have different particularities and have to be 
independant from each other.

So my question is: How can I present two kinds of stimuli controlled by 
two idenpendant lists at the same time?

Hope my question is not too messy. Thank you in advance for your help!
Best,

Dear all, 

Does anyone know how to present a stimulus for the same duration that a key
is held down. That is, the stimulus should appear with the press and
terminate with the release. 

Many thanks.

How do I get the list object name so that I can get some attributes from

In other words, I want to record the Sample number in a text file, but I 
need to get the list name so that I can get one of the list's attributes 
right, as in c.GetAttrib("ListName.Sample").

How can I get eprime to tell me what list I'm in?

Thanks,

Hi Leisha,

This should do exaclty what you need:

c.GetAttrib(c.GetAttrib("Running") & ".Sample")

Hi all,

I'm hoping to set up an experiment in which the same slide event varies 
between a timed and infinite duration but I'm having trouble getting 
the event to accept "infinite" or "(infinite)" as acceptable durations 
specified in a list.  

I realize I could put a long duration value into the list in the hopes 
that subjects don't wait too long during the event, but if possible I'd 
like to specify a genuinely infinite duration.

Dear Leisha,
If I remember correctly, there were some issues with refresh rates of laptops so
that timing may not be as accurate as you want.  This may be neglibile for
decision research.  You may want to have a regular CRT to plug into.  I think
some of this is addressed in the list serve archive.

Leisha,

I have been playing with several older IBM Thinkpad Laptops -- these are
some of the finest PCs available, although they are rather pricey when
brand new. They are rugged, reliable machines that won't let you down. I
have not tried to put E-Prime on these machines, but I might try that in
the future. The Thinkpad would be my first choice as a portable platform
for experiments. They are also highly modular, and easy to modify (
CPUs, batteries, memory, drives ) I will be happy to give you basic
information about the various types of Thinkpads out there and discuss
this further, if you want to email me off list.

We ran RT experiments with EPrime on Toshiba Satellite Pro laptops, because 
that was what was already being used in the larger study that we're a part 
of.  My testing showed no crucial timing problems, and the examiners in the 
field have not complained of problems running our programs.
Maybe I should add that the stimuli were entirely auditory, so screen 
refresh rate, etc, was not an issue.  Also, we used the response box.

Hi, Dr. Wright,

For you and for the list, here is a synopsis of the replies I've 
received to my laptop queries so far. I've received recommendations for

1. Toshiba Satellite Pros, on which Carol A. Miller actually ran RT 
experiments with eprime.

2. Dell Inspiron
    + Dell again, with the caveat to use the AC power rather than the 
battery, to avoid timing issues. Thank you, Mr. Bigio.
    + Dell Inspiron, recommended by Kim Lesniewicz. However, her Dell 
has a wide screen that stretches text, and we wish to avoid this. Also, 
she has found it necessary to reboot her laptop after each run to solve 
a freeze-up issue, and I don't wish to ask our experimenters to do this.
    + Lee Hogarth recommends a Dell Latitude D505, saying it has never 
failed her. Actually the Dell Latitude D610 meets our present 
specifications, but I think I can do better on price.

3. IBM. Highly recommended. I agree with Dr. Sudevan that they are 
rugged & reliable, but he has not used them specifically with eprime.

4. General issues. Dr. Crowley reminded me to check the archives for a 
discussion of timing issues on laptop computers, including refresh rates 
and use of AC power versus battery.

5. A final issue to add: We use input devices that were made for our RT 
experiments. They are large switches or buttons, one for each hand, that 
can be pushed easily and give a solid clicking sound. They are wired 
into a serial device because when we began this series of RT computer 
experiments, we were told that the serial port was the cleanest, 
quickest way to get to the processor and we are measuring very fine time 
differences. Now serial ports are hard to come by on laptops, and when I 
read about new laptop connectors I find that the now-standard FireWire 
IEEE 1394 is a port that was designed for using a computer in "real 
time," that is, to play 3D games or to interact with streaming video. 
Wouldn't this now be the best port for measuring very fine time 
differences? Or is serial still the best way to go?

I'll post another synopsis of replies received.

Thanks for all your help.

Thanks. I'm looking at 2 gigs of memory for each laptop. I'm loading 
multiple images per slide, too. But I can load the background first, 
pause, then load the actual stimulus. This should help me control 
refresh time, but how do I measure it to be sure?

This does help. The experiments we are running are actually very simple, 
and I will review the critical timing information for eprime to be sure 
I understand your method.

hello Leisha,

A small note on ?real time? issues:

Since marketing people like to use ?sexy? words to promote additional 
functionality or suggest superior specifications, we have to be a bit 
careful how to interpret the words ?real time? correctly. The actual meaning 
depends on the context: Most hardware and software engineers use the words 
?real time? to indicate that the time allowed to execute some kind of 
operation is limited to a known maximum. Some engineers also differentiate 
between so called hard and soft real time. In hard real time systems it is 
an absolute system failure if the real time criteria are not met. (Ie. the 
air bag in a car is definitely a hard real time system.) In soft real time 
systems the real time criteria are less strict. This is the case with EPrime 
where it is sufficient to keep track of such timing failures. (See also 
http://en.wikipedia.org/wiki/Real_time) Anyway, this kind of real time is 
about the response time limits of a system, not its execution speed or 
bandwidth.

Real time streaming media protocols on the other hand, are said to play 
media in ?real time? when it is possible to play the media stream at the 
correct speed (ie. not in slow motion.) So, in this case marketing people 
and engineers refer to the large bandwidth or execution speed of the system, 
not maximum response latency. In other words: even though Firewire and USB 
standards support large bandwidths, this does not mean that they support 
short (<1ms) transmission delays. Furthermore, the complex protocol stacks 
that are used to implement those communication systems make it almost 
impossible to realize short latencies. But even if you are willing to accept 
timing errors, it is not very trivial to develop hardware that connects 
through USB or Firewire. RS232 and parallel ports are much easier to use in 
both hard- and software.

There are some real time systems that use another common connection between 
de external hardware and the computer: Ethernet. A (dedicated) Ethernet 
connection supports high bandwidth and short transmission latencies. 
However, as with USB and Firewire, it is not very easy to develop hard- and 
software for such a connection. (Note that PST writes it will support some 
kind of Network Socket Device in version 2.)

Hi Leisha,

The serial port is fine. Although in most cases the parallel printer port 
and the game port are also usable. This is the case when the buttons are 
connected 'directly' to the input lines of the port (not the serial Rx/Tx 
transmission lines) and a 'Port' device is used in EPrime to scan the 
corresponding IO register. (See also 
http://www.psy.vu.nl/download/menu/index.html)

Note that the PST Serial Response Box uses a different technique to send the 
button states to the serial port. In this case a sequence of bytes is 
transferred to the Rx line of the serial port. It is not very likely that 
your button box uses this serial protocol because it requires additional 
electronics and software.

best,
paul

Thank you, Paul. I checked out the link you sent me. My serial device is 
not a box at all--it's two buttons designed for people who have physical 
limitations. They are about 2-1/2" in diameter and very easy to press, 
resulting in a clear audible click. There's no box at all: the buttons 
are wired into a serial connector that I bought at Radio Shack. The 
buttons are configured as a port device where the left button returns a 
5 and the right button returns a 6.

Does this sound similar to how the PST Serial Response Box works?

Your advice has been extremely helpful. I will be able to answer all the 
technical questions that are thrown at me about this purchase when the 
time comes & make my recommendation with more confidence, thanks to you.

Sincerely,

Leisha

But haven't people suggested a couple of ways to display video as part 
of an E-prime script in the past? I mean, suspending E-prime & calling 
out other executable files, chaining a bunch of bitmaps together to 
create a video effect, or creating some kind of dual-monitor display?

 As far as I'm aware, E-prime doesn't handle multi-byte fonts (e.g.
Japanese) very well.

When constructing a script in japanese, I use Word and Arial Unicode to make
the sentences, and then Paint Shop Pro (or Print Screen and Paint, for a
free alternative) to grab screenshots, and use picture stimuli instead of
text stimuli.  This is the same technique I used with Psyscope - 1.2.2 under
OS9.x used to whimper if Greek fonts were used, but I digress...

A bit of a hassle, but it works well here (and as here is Linguistics rather
than Psychology, it's not too unusual...).  If anyone has a better way, I'm
all ears....

V2 of E-prime is meant to address this issue..

Hi,
I'm a Japanese student using E-prime, I know a tip to display Japanse
fonts with a TextDisplay object.
My suggestion is to implement text stimuli directly in the EBS file.

Your .ebs file should have a line to 'InitTextDisplayDefaults' as below:

theTextDisplay.FontName = "..."

Change the font name ("...") into the one which can handle Japanese
characters.

Then you can write in Japanese the content of each TextDisplay object,
e.g.;
TextDisplay1.Text = "...(in Japanese)..."

That's it. 
Now you can run the script.
Does it work?

Hiro 

# Still, it's a lot of work when you have a large number of item to
  display. I think most Japanese users don't take this way, instead
  use the  ImageDisplay to present Japanese words, as Eddie discribed.

Subject: problem with summation object
Message-ID: <FRI.20.JAN.2006.121332.1100.HESTERR@UNIMELB.EDU.AU>

To the mailing list,

I have been successfully using the summation object script (available on 
the e-prime website) to collect and average the number of correct responses 
from 100 trials, but I've run into a problem when I changed the stimulus 
timing properties of the task.
I've have a flanker task setup so that the stimulus display object is 
presented for 100ms and then changes to a second stimulus display object (a 
blank screen) while it waits for the participants response. I have the 
stimulus display object 1 response properties configured so that it runs 
for 100ms (cumulative timing with 100ms) with the response input time limit 
set to 'infinite' and end action set to 'terminate'. Stimulus display 
object 2 does not accept responses, but is set to an infinite time limit. 
The summation object in line script is placed after Stimulus display object 
2 (although it doesn't matter if I move it to after SDO1), and reads:

'The AddObservation command adds the ACC value of object
'StimulusPresentation to the Summation object, OverallAcc.
OverallAcc.AddObservation c.GetAttrib ("stimulus.ACC")

'The Debug.Print command prints the mean value of the Summation
'object, OverallAcc, in the Output window.
Debug.Print OverallAcc.Mean

'The OverallACC attribute adds the running calculation of overall
'accuracy to the data file at the trial level.
c.SetAttrib "OverallAcc", OverallAcc.Mean


How does having the second display object interfere with this script, 
because removing makes the summation work perfectly? Anyone got a suggestion?

Cheers
Rob

Hello Rob,

I don't think the problem relates to the summation object itself. In some 
cases the values of attributes are not set properly during the script. 
Instead, you could use the parameters of the corresponding EBasic objects 
directly. It is in some cases also required to manually terminate an 
infinite response. Just try the following:

If stimulus.InputMasks.IsPending Then stimulus.Terminate
OverallAcc.AddObservation stimulus.ACC

To validate this, you could add some test code before the two lines above:

Debug.Print "---- "
Debug.Print "pending: " & stimulus.InputMasks.IsPending
Debug.Print "acc:       " & stimulus.ACC
Debug.Print "acc$:     " & c.stimulus("stimulus.ACC")


Cheers,
Paul

Subject: Slide simultaneously displaying 2 stimuli from 2 independant lists
Message-ID: <TUE.24.JAN.2006.105406.0100.CDEVUE@ULG.AC.BE>

Dear E-prime users,

I'm trying to display a slide composed on each trial of a different face 
and of a pair of different numbers.
The faces have to be different in each trial and randomly appear on the 
right (half of them) or on the left (the other half). These faces have 
to appear in a particular sequential order. Regarding the numbers, there 
are 4 kinds of pairs and they have to appear in a random order.
The subject's task is to respond to numbers while ignoring the face.

Thus, the point is that one face and one pair of numbers have to appear 
on the screen AT THE SAME TIME (and same duration).
To do so, I have tried to make a list, let's say 'DisplaySlide List', 
with 2 Nested lines, to obtain a sublist for faces and another for numbers.
Then, I insert a Slide in the TrialProc (defined in the DisplaySlide 
list, and I've even tried it with a higher order additional list) 
appealing a face AND a pair of numbers from the two sublists. But it 
does not work.
When I try to run the experiment, I obtain an error message (saying that 
it cannot find one column refering to either a face or a number). 
Nevertheless, I know that there is no problem with each idenpendant 
sublist (because a made 2 scripts with each one in order to check, and 
each of them work as i want).

As I can understand, Nested Lists make the different items within the 
different lists appear sequentialy. So I think, this is not the good way 
to make the face and the numbers appear at the same time. But i do not 
know the right way to do it.
However, I think I had to make these two different lists for faces and 
for numbers because they have different particularities and have to be 
independant from each other.

So my question is: How can I present two kinds of stimuli controlled by 
two idenpendant lists at the same time?

Hope my question is not too messy. Thank you in advance for your help!
Best,

Dear all, 

Does anyone know how to present a stimulus for the same duration that a key
is held down. That is, the stimulus should appear with the press and
terminate with the release. 

Many thanks.

Lee Hogarth.

Hi, all,

How do I get the list object name so that I can get some attributes from 
a list running a procedure that runs from a few different lists in my 
experiment?

In other words, I want to record the Sample number in a text file, but I 
need to get the list name so that I can get one of the list's attributes 
right, as in c.GetAttrib("ListName.Sample").

How can I get eprime to tell me what list I'm in?

Thanks,

Leisha

Hi Leisha,

This should do exaclty what you need:

c.GetAttrib(c.GetAttrib("Running") & ".Sample")
