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

Since 2004, a number of small changes were made to the automask function. Perhaps you are seeing the effect of the 'peel/restore' option (added about a year ago), in which the outer layers of the mask are peeled off, then any small clusters cut off from the main body by that operation are excised, then the remaining peelings are restored. The default is to peel/restore one layer -- previously this operation was not done. You could try '-peel 0' if you want to see the difference. The other difference is the '-nograd' option (the former default), as you pointed out.

Are you really worried about a voxel or two?
