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

Hello,
This is what I have been doing up to now but I came across a precision issue. I'm working with very small fractions so my nzmean is already below the precision that 3dROIstats outputs. By the time I multiply it with nzvoxels I get 0 as the result. I'd still like to ask if it's possible to have a sum option in 3dROIstats.
Thanks a lot,
Stathis
