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 Heather,

You probably have 2 runs of data, are using a linear
polynomial for baseline, and have a significant shift
in the white matter regressor. What does the white
matter regressor look like? Assuming it does have a
shift, the "why?" would depend on the pre-processing
steps, which we do not know.

I take it that you are not using afni_proc,py for the
analysis. It might be a good idea to use it, at least
for comparison.
