stimulus right or left

[liwenna]

Hey Eli,

Unfortunately there's no way to ensure a 4cm distance on any screen. X
and Y coordinates can be given in percentages of the screen (as in
your script) or in pixels (i.e. if you would take out the % sign, your
x value would become 32th pixel or 68th pixel).

When e-prime runs a script it will 'take control' over the
displaysettings and adjust it to the values set in the script. By
default this is 640 x 480. You can adjust these settings by clickinng
the e-prime logo at the top of your experiment tree and then go to the
devices tab and edit 'display'. I suggest you and everyone else to do
this right away when you start a new experiment. The exact distances
between two pictures or between a picture and the midline of the
screen is decided by size and resolution of the screen. By fiddling
around with the x values you can set e-prime to show the picture on
4cm from the midline on your screen and this will be 4cm on any screen
with the same size, but if the screen you run e-prime on is different
in size, the distance in cm will vary accordingly.

The above is no 'solutions' just a description of what e-prime
'does'.

Best,

liw
