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

Your approach is one method. This would work with relatively well-separated in time stimulus epochs, but might not work well with interleaved event-related stimulus designs.

An alternative to casting out the unwanted baseline is to create a GLT (general linear test) modeling the differences you want to test. This is done with the "-glt" option to 3dDeconvolve. The 3dDeconvolve manual explains this in detail and has some examples; and the 3dDeconvolve HowTo has some data and examples.
