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 there are several runs in an fMRI dataset, AFNI seems to add a different set of detrending regressors for each run, but there is only one set of activity regressors and one set of motion regressors. SPM, on the other hand, seems to add one set of activity regressors and one set of motion regressors per run.

I'm not saying that either way is wrong, but it would be interesting to know why AFNI uses the first option.
