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 Michael,

Most regressors should have discontinuities at the
run breaks.

The stimulus regressors should break between runs
because BOLD responses do not cross runs. The
polort regressors should model the drift per run
for a similar reason, slow drifts or fast, they
are still discontinuous across run breaks. The
motion terms can be modeled either way (depending
on the options given to afni_proc.py, for example),
because at least they coincide with the TRs.

Let 3dDeconvolve know about the run breaks.
