Hi Isa,
Are you running afni_proc.py through regression? If so, then I
don't really see what you would gain from naming the EPI datasets.
The labels for the beta weights are what one typically cares for.
Otherwise, would you provide some more details about exactly
what you are hoping to do? Are you just using afni_proc.py for
preprocessing, and then running your own pair of 3dDeconvolve
commands?
