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 think that "3dTcorrelate" provides the most similiar function for this purpose. However, for canonical correlation, the calculation should not be between corresponding voxels but between corresponding ROIs of "xset" and "yset". Namely, I want to move a spherical ROI (user defined radius) in the brain with the output reporting voxel-wise canonical correlations. I was trying to do this with matlab but it's very slow. I am wondering if "3dTcorrelate" can have a new option of "-canonical" in future updates.
