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.
That sounds fine to me. Changing the actual coordinates would change the reference system, but if you were creating a new atlas, that might be a better way. For the zeropad idea, you can do this a bit more automatically with 3dAutobox using a brain mask and then 3dZeropad with the autoboxed brain mask as the master. Add a few slices around to allow for alignment of other datasets.
