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.
In any case, even starting in MNI space, to have a consistent
number of voxels, be sure that the ROI centers are exactly on
top of voxel centers. Otherwise, the sizes might still vary,
depending on how coordinates happen to fit between the voxel
centers.
