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

If you can't wait for Rick's improved script, you can try 3dretroicor. I haven't worked on it in several years, but it's still there. Your mileage may vary. Subtract the output from the input dataset to see what it did to each voxel timeseries.

If you take the (optional) phase outputs from 3dretroicor I believe you can calculate RETROICOR regressors yourself by simply computing the sine and cosine. The annoying part is downsampling the regressors to the times of slice aquisitions. Maybe I could add that to 3dretroicor sometime.
