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

3dMatch is not a straightforward correlation coefficient, it is a weighted one (-> to emphasize larger values in the data sets during the matching part). Therefore, I think 3ddot would be a better choice if that is the specific quantity you want. I guess the straightforward correlation coef value could (and perhaps should?) be added to the 3dMatch output text file.
