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

3dROIstats computes statistics for each value in the mask dataset. So if the mask dataset has multiple values, the requested statistic will be computed multiple times corresponding to the multiple columns in the output. My guess is you did not use -preserve (or -vote) in your 3dfractionize command and ended up with various interpolated values in your mask dataset.
