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 Philippe,

You are a little ahead of the game here...

Ziad has the RetroTS.m matlab function to create RETROICOR
regressors. To go with that, I am adding a processing block
to afni_proc.py that will remove those regressors from the
EPI data.

Those regressors will be removed before volume registration
or time shifting (but after despiking), since accurate timing
is essential.

3dREMLfit is used to remove those slice-based regressors.

The update to afni_proc.py should go out next week sometime.
