Hello,
I have two resting state runs for the same subject, but when I pass them to afni_proc using -dsets rest* neither of them have enough TRs after censoring to run 3dDeconvolve. There's a chance I'd have enough TRs if 3dDeconvolve were run on a concatenated time series. (this is a generic description - we have several subjects in such scenario and the number of TRs left after censoring varies by subject).
How would you go about concatenating these files before running afni_proc (e.g. scaling, time shifting, polort regression)? Or are there any flags in afni_proc I'm missing that would take care of that (below, but mostly example 11)? In general, is it even a good idea to do this?
Thanks,
Gustavo
