You should be able to use "whereami -show_atlases" to see all the available atlases and their corresponding template spaces. If you want all these to show up in the Draw Dataset plugin, set AFNI_ATLAS_LIST to ALL in your .afnirc file. The CA_N27_ML or CA_N27_MPM atlas may be what you want. The atlases with names ending in MNIA are not in MNI space, but in a variant of MNI called MNI_ANAT space with the (0,0,0) at the Anterior Commissure. You can also use a copy of an atlas, or extract a particular region with 3dcalc. If you have atlases available elsewhere, these can be merged into standard AFNI use by using the script @Atlasize. Let me know if you run into any problems.
