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

I'd start by combining all of the ROIs in such a way that you'll get a separate value for each one. You can follow some of the instructions laid out here. The key is to create a dummy (empty ROI) and then use 3dTcat to concatenate all of your ROIs together with the empty one first. You can then use 3Tstat with the -argmax argument, which will result in a single NIFTI (or HEAD/BRIK) that has all of your ROIs, each with a unique value.

As for mapping that file to the surface, you can use 3dVol2Surf to do that.
