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

Perhaps you could do 3dDeconvolve with -iresp first, which gives you voxel-by-voxel impulse responses for each stimulus type. Then each frame (i.e. each sub-brick) of each impulse response is the average signal for that stimulus type at that lag, voxelwise. Then 3dmaskave will convert that from voxelwise to averages per ROI.

So you'll end up with a separate BRIK file for each ROI, for each stimulus type. Within each one, each sub-brick will be the average signal at that sub-brick's lag.
