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 Peter,

Thanks for your input.

It's still unclear to me using -paired option. That is to contrast two sessions, which is not what I am interested in.
I want to see a main effect of stimulus onset activity (against 0) in overall collapsed across two sessions. Also entering covariates would be subject-wise, not session-wise in 3dttest++, which I assume covariate regressor would not be able to account for the inter-session variability..?

It would be much appreciated if you could provide more detail - maybe I'm missing some options...

Thanks a lot for your help.
