Hi,

I don't see where I was advocating for using 3dQwarp rather than @SSwarper itself. I described the properties of 3dQwarp because it is used as *part* of @SSwarper, not because I thought it should be used instead. @SSwarper will *both* skullstrip and align to standard space-- two things that we have found useful to do together. So, I would use @SSwarper in general, as a precursor step to afni_proc.py.

Your questions:
#1- what is the output of:

afni -ver

? The "-lite" functionality became default in 3dQwarp Jan 8, 2019, so a version after that would be running "lighter". But again, you want a bigger desktop to use when processing a group.

#2- if you didn't want to use @SSwarper (but I haven't seen a reason why you would?), then you would just use this option in afni_proc.py (while also having 'tlrc' as one of your blocks):

-tlrc_NL_warp

Again, to be clear, I am *not* recommending this, unless there is something I have forgotten from the earlier thread?
