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 Gang,

When you say that "FMRI data are not suited for causal modeling through GCA" do you mean all kinds of fMRI data (including resting state) or are you specifically referring to task-based fMRI?
I thought the afni tools 1dGC and 3dGC addressed some of the issues of temporal resolution, or am I wrong?
Are you suggesting that we should not perform Granger Causality with any kind of fMRI data?

Best regards,
Sam
