stim_files in afni_proc - no basis function

AFNI Message Board

Hi there. I’d like to use afni_proc.py with no basis function at all. The data are from a sparse temporal sampling experiment, so each TR corresponds to exactly one stimulus. If I were going to create a 3dDeconvolve command manually I’d put the series of 1’s and 0’s (for each condition) in with the -stim_file option, but afni_proc.py seems to convert them to stim_times and use the GAM function by default. Is there a way to get afni_proc.py to put the stimulus regressors in as raw 1’s and 0’s? Thanks.

Apply “-regress_stim_types file” in that case.

Ah, not sure how I missed that in the ‘help’. Thanks.
