BTW you can also google it as sub-list e-prime or something like that. I am sure PST forum or this list discussed this or similar topics before.<br>Meltem<br><br><div class="gmail_quote">On Fri, Oct 14, 2011 at 9:39 AM, Meltem BALLAN <span dir="ltr"><<a href="mailto:meltemballan@gmail.com">meltemballan@gmail.com</a>></span> wrote:<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Gautam,<br>I have an idea. You can prepare two lists (one for the right and the left and second for the middle images). Then, you might want to call those files (edit->properties->startup info). Lets say for session 1<br>
call fileLR and shuffle the list (list properties->order->random). <br>In order to show 20 models you can count to 20 and jump to the end of session (I would use goto) <br>repeat it for session 2 including the middle images. <br>
I hope it helps.<br>Meltem<div><div></div><div class="h5"><br><br><div class="gmail_quote">On Fri, Oct 14, 2011 at 8:56 AM, Gautam Malu <span dir="ltr"><<a href="mailto:gautam.malu@research.iiit.ac.in" target="_blank">gautam.malu@research.iiit.ac.in</a>></span> wrote:<br>

<div>1_right_pose.jpg</div><div>1_left_pose.jpg</div>
<div>1_middle_pose.jpg</div><div> ............................ total 60 images</div><div>Experiment consists of 2 phases</div><div><br></div><div> -->1st in learning phase, in which participants will see 2 poses of any 10 models.</div>

<div>how can i get this type of ordering in learning phase</div><div>Example</div><div>3_right_pose.jpg</div><div>7_left_pose.jpg</div><div>11_left_pose.jpg</div><div>3_left_pose.jpg</div><div><br></div><div><br></div><div>
