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.
Even if it is theoretically possible, it means that every
voxel (in your mask) is below some limit that you are
actually applying.
If you look at a small ROI, and/or with a relatively
large amount of blurring, perhaps that might happen.
How many voxels are in your mask? And consider
running 3dhistog.
