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

Were the separate scans performed in the same "session" or the subjects got out of the scanner in between? If they got out of the scanner, simple concatenation won't work. You can register both scans to their own anatomies, and then to each other. The help for 3dvolreg provies some instructions as to how to do it.

An alternative is to do separate 3dDeconvolve on both scans, and then compare the conditions with
3dttest -paired -set1 <scan1 list> -set2 <scan2 list>
