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

According to the documentation, 3dmaskave or 3dROIStats "lets you compute the average over a ROI of *all* voxel values from an input dataset."
Is there a way to compute the average over only those voxels in the ROI that are above a particular threshold ?
Possibly using 3dmerge somehow? Thanks for your help.
