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:

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 Rick,

Thanks a lot for your precious guidance ! I run the command that you recommended me and indeed, it found a very 'basic' typo error.
Everything went then perfectly once I could correct for it.

Just a last question about how to interpret correctly the map that I got with the inclusion of the covariates. If I select a contrast with one of my covariate, let's say the BDI score which is a score of the severity of the symptoms characterizing depression and which has been centered, I get a deactivation between the Nucleus Accumbens (NAcc) and the PCC. I am wondering whether the right interpretation in this case is (1) once we control for the severity of depression symptoms (characterized by the score at the BDI questionnaire), we get this connectivity map, (2) the higher the BDI score, the lower the connectivity between the NAcc and the PCC or (3) the lower the BDI score, the lower the connectivity the connectivity between the NAcc and the PCC ?

Thanks so much !

Best wishes,

Claudie
