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.
I already had a look at the 3dinfo information, but in case of 3dAnatNudge, I can see only something like "3dAnatnudge -verb -anat brain+orig -epi epi+orig -prefix nudge", but not the actual translation parameters. Furthermore, I am not quite sure, if 3dAnatNudge does something else like setting the origin to zero etc... For the nudge plug-in, it is easy as you suggested to get the information.
