AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

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.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

This is a little confusing to me. Are you trying to find a center for a surface, a patch on a surface or a volume? Surfaces are typically stored in GIFTI files ending in .gii. NIFTI files are most often used with volumetric data. Patches are usually a list of nodes in a niml.dset, 1D.dset, .1D and sometimes in .gii format as a "functional" GIFTI.

We had a poster on different ways to compute centers at last years OHBM.

If you provide some more detail, I'd be happy to point you in the right direction.
