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

Hi Carole,

So for each voxel in the brain, you want the correlation
with each of the 503 voxels in an ROI? That would be a
503 x 100000 element matrix, say. Is that right?

If so, then maybe 3dAutoTcorrelate will do that, where
the 503 voxel mask might be provided via -mask, and the
brain mask might be provided via -mask_source. Note that
the output would be a 530 'time point (voxel index)'
brain-masked dataset.

Please see the -help output for details. The 'Example'
there might match what you are doing.
