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 for your reply, Gang!

Your reply illustrated how to average the time series over a Region of Interest, but can 3dDeconvolve generate a 1-D hemodynamic response function?

I used the -iresp option in 3dDeconvolve and it created a HEAD+BRIK dataset for me. When I opened the dataset in AFNI, it ended up looking like a 2-D activation map. Where can I find the 1-D response function for each voxel?

I've attached a couple screen shots of my output from 3dDeconvolve when opened in AFNI.

My question is: How do I get a 1-D hemodynamic response function for each voxel? Is there a way I can select the activated voxels according to the map and get a impulse response function for my selected voxel?
