Hello AFNI experts,
I am encountering an issue when attempting to run a script based on @stim_analyze.
More specifically, when I run the script I get the following message:
** removing output directory, stim_results ...
++ creating output directory, stim_results ...
iteration (of 100): 0000nums: Subscript out of range.
The directory stim_results gets created, but I think the issue has to do with the foreach loop, as when I try to run: iter(`count -digits 4 1 $iterations`)
I get the error: Badly placed ()'s
Any idea what I am doing wrong?
Thanks a lot for your help!
Laura
