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

The transformation matrix is the *.Xat.1D output from @auto_tlrc. After generating a partial mask for an ROI in tlrc space, I wanted to take the ROI back to orig space. It seemed that this task perfectly matched the example in 3dWarp (copied in OP); yet, when I applied it, it only worked if the switch for 3dWarp was -matvec_in2out. Of course, the end product is up to snuff. Maybe the Xat.1D is already inverted, and I simply didn't read the @auto_tlrc -help carefully enough?
