Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

Hello AFNI community,

I am trying to extract Destrieaux ROIs from data that was processed using an older version of AFNI/SUMA. The data has already been processed through suma (i.e. @SUMA_Make_Spec_FS, @SUMA_AlignToExperiment, etc.). When attempting to extract and combine ROIs from aparc.a2009s+aseg_rank_Alnd_Exp, e.g. using 3dcalc, I get the following error: 
$ 3dcalc -a aparc.a2009s+aseg_rank_Alnd_Exp::ctx_lh_G_pariet_inf-Angular -b aparc.a2009s+aseg_rank_Alnd_Exp::ctx_lh_G_pariet_inf-Supramar -c aparc.a2009s+aseg_rank_Alnd_Exp::ctx_lh_S_interm_prim-Jensen -expr a + b + c -prefix lh.InferiorParietal.cortical
++ 3dcalc: AFNI version=AFNI_21.1.02 (Apr 16 2021) [64-bit]
++ Authored by: A cast of thousands
*+ WARNING: Proceeding with hope for an impossible miracle...
** FATAL ERROR: can't open dataset aparc.a2009s+aseg_rank_Alnd_Exp::ctx_lh_G_pariet_inf-Angular
** Program compile date = Apr 16 2021

The labels for aparc.a2009s+aseg_rank exist (e.g. they appear when whereami is called from <subj>/SUMA). If my goal is to extract ROIs from aparc.a2009s+aseg_rank_Alnd_Exp, how might I go about this?

Thank you so much!
