Hi freesurfers,

I have an event-related design experiment which outputs a file with a line corresponding to every TR.

i.e. for TR = 1 the first 3 columns of the file look like:

0 0 1 1 0 1 2 0 1 3 0 1 4 0 1 5 1 1 6 1 1 7 1 1 8 1 1 9 1 1

Assuming I have 5 seconds of fixation followed by seconds of condition 1.

Is this the correct way to format this file? or should it have aline for every condition onset such as:

0 0 5 5 1 5

Perhaps, it makes no difference. Please let me know if you have insight into this

Thanks,

Cesar
