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

Hello again,

3drotate has been modified to store the transformation in the output dataset's header and SUMA has been modified to use them.
In other confusing words, if you align your surface volume 'SurfVol' to your experiment's anatomical volume 'ExpVol' using 3drotate, the output dataset ('SurfVol_Alnd_Exp') contains the transform necessary to bring the surface models into alignment with your experiment's data.

In yet more confusing words, the changes makes what Kai was trying to do via 'Nudge Dataset' and 3drotate work.

The reason 3dvolreg was failing is the large difference in coverage between the surface volume (SurfVol) and the experiment's anatomical volume (ExpVol). In such cases, manual alignment is the way to go.

Binaries with fixes will be available sometime this evening.

cheers,
-ziad
