That does not work either for me:
whereami -atlas ARM"[3]" -bmask Clust_mask_0001+tlrc
++ Input coordinates orientation set by default rules to RAI
** ERROR: Atlas ARM[3] not found in list.
but again ARM seems to register each level separately in afni so
whereami -atlas 'ARM Level 3' -bmask Clust_mask_0001+tlrc
works fine.
I am now seeing some discrepancies between what whereami shows vs. my Matlab script - which I wrote anyway, to get the percentage of atlas regions covered by each ROI. Most likely I made a mistake in the script, but if I cannot reconcile the results, I may come back for help...
Thanks again,
Pawel
