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

Hi Yaelan,

Have any trends already been projected, or any tedana regressors?

In general, provide -polort 0 and as many -ort and/or -dsort terms as you wish (where -ort files can have multiple columns). If no drifts have been projected already, then you might consider a -polort option that would be equivalent to that for 3dDeconvolve, i.e., 1+floor(run_length/150).

Detrending should be done in the same 3dTproject command, if it has not already been done. Actually, it should probably be done either way, since the motion terms might have trends in them.
