Hi Rick!

Really thanks for your reply!

For your first question, they aren't consecutive short events but single longer (6 s) events. That is to say, each event lasts for 6 seconds(e.g. first 6s showing a "L" on the screen is to ask subjects to do left hand task within the 6s, no matter how many tasks they can perform within the 6s and the same for right hand). And what do you mean by using longer response functions? Like TENT(b,c,n) to make parameter c as longer?

For using TENT(0,6,4), since each event lasts 6s, therefore I assume that the subjects can response within the 6s. If exceeding 6s, they may be asked to do other tasks. (The whole process is to ask subjects to do left or right hand task or keep rest within the 12min) So c is 6 and TR is 2, then n is 4.

And rest_time.1D, yes, just represents the time points that are not part of left_hand_time.1D and right_hand_time.1D. But if it is not be included, how can I use "gltsym" to do contrasts with the rest baseline ones? I've tried without rest_time.1D file and just find the results are not reasonable. I mean, when I chose Thr, like "lefthand#0_Tstat", on ANFI to see clustim results, all areas are included no matter small p values... Or did I use a wrong way to look at the results?

Looking forward to your reply. Thank you Rick

Best regards,
Tracy
