Hi PT,
No but those atlases are quite large and AFNI might be loading too many of them. There are ways to trim this by hiding some of the large atlases that you don't need from AFNI's sight (move them out of abin/ for now into some other directory). The better solution involves setting your preferences to load just a few of those atlases even if you have a ton available to AFNI. But I will let Daniel elaborate on that since he has been the one working on this recently.
cheers,
Ziad
