Hi Rick,
Thanks so much for the reply. I tried doing that, but the script threw a few errors related to missing tlrc options. I probably wasn't particularly careful with modifying the rest of my call! I'll give it another go.
One more related question, if you get a second: let's say I wanted to use the tlrc option, but would also like to be able to view my statistical maps in both talairach and original space (the latter option perhaps being useful for subject-level multivariate analyses). Is there an easy way to accomplish this using afni_proc.py?
Thanks again!
