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 rotation in 3drotate is always about the center of the 3D rectangular volume defined by the dataset grid. The proper way to use 3drotate to apply a given transformation is then to cast your transformation matrix+vector into this system. If you want help working out the math, then I'll need more details about your application. E-mail would be better for this, probably.
