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 have looked at this, and there are more subtleties. Basically, the param files between 3dvolreg and 3dAllineate are not appropriate for passing between the programs. Besides the column order, there are appear to be negatives between the shifts. Also, 3dvolreg uses the center of the volume for rotations, while 3dAllineate uses xyz = (0,0,0) for its center. So the sets of rotations/shifts will not equate, even if they are "properly" rearranged and signed.

This brings up why both programs have -1Dmatrix_save options. The matrices translate better than the parameters. I will compare those, too...
