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

Hi Michael,

3dSeg seems to be complaining about NaN values in
the dataset. Most AFNI programs were not written
to process that in some special way, so I suggest
that you zero out those values ahead of time.

Consider using @float_fix for this.

I am not sure whether 3dSeg has an option to skip
its internal bias field correction, but even if so,
that would probably just postpone NaN issues until
later.
