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

To be sure, is this regression and difference being done just within the ROI mask? Are you taking an ROI average, regressing out motion, and then using the resulting TR differences for feedback?

If so, consider regressing the motion parameters from the entire ROI average time series, not just from 13 TRs. Only after this might you extract values for the 13 time points of interest, using the relevant ones for feedback.

Is that feasible?
