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

I believe the -fraction option of 3dToutcount will give you what you need.

3dToutcount -automask -fraction epi+orig.

Automask should reduce to the number of voxels in the EPI. But you could also supply your own mask. If you run 3dToutcount without a mask, then you will be asking for outliers both in the brain and outside of the brain. You can get the total number of voxels by running 3dBrickStat:

3dBrickStat -count epi+orig.[0]
