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

You can do it by extracting the cubic column(s) from an xmat.1D file created with 3dDeconvolve -polort 3 -x1D_stop and adding that as a -ortvec to a 3dDeconvolve -polort 1, though there's probably an easier way. I'm not convinced it's a good idea, though, since it effectively amounts to assuming that the inflection point of your scanner's drift occurred halfway through each run.

My intuition on this is probably not as valuable as that of other people on this board, though.
