Hi John,
Ziad wrote a RetroTs.m matlab script for creating regressors
that can be processed via afni_proc.py. That's how we deal
with it in AFNI-land. Fred Tam has also suggested 3dretroicor.
Consider this thread:
[
afni.nimh.nih.gov]
Also consider "3dretroicor -help".
Also consider "afni_proc.py -help", incluing "RETROICOR NOTE"
and the RETROICOR examples (5a, 5b).
