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.
I would like to subdivide a region into clusters of voxels with high correlations between them. What's the best approach to do this? Is there an afni function that can help me with this? or do I have to calculate the correlations for each voxel? I was just reviewing 3dClusterize and 3dMerge, but they don't seem helpful for what I need.
