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

Hello,

I am familiar with afni's volume-based tools, but I have no shifted toward using surface-based tools from freesurfer and CONN toolbox. In order to upload an visual cortex atlas consisting of 50 ROIs I first converted it to a .nii file. I'd now like to determine the coordinates of each ROI center of mass. For a volume-based data set I would use something like 3dClust. However, SurfClust does not allow .nii files.

Is there a way to obtain surface ROI information from .nii files? Or to convert a .nii file to the spec and surface files required for SurfClust?
