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

Thanks, how would I go about finding out how many voxels (i.e. what percentage of voxels) contain at least one spike? Im thinking it will involve spikesum+orig from above. Can I just count how many voxels in spikesum+orig are non-zero? Also, am I correct that despike uses an automask, so if I want to express this count as a percentage of voxels, what should be in the denominator?
