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

3dAutomask starts its work using the histogram of the voxel intensities. After scaling, this histogram contains so little information that the algorithm used for selecting the initial threshold doesn't work well. I suppose the algorithm should adjust to the weird (non-smooth) nature of the histogram, but is it really worth the effort?
