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

JoJo,

No, that would not give you statistics for the new contrasts.

It's possible to use 3dcalc to obtain them if you know the formula. However, it would be easier to just use 3dDeconvolve. If you've saved the design matrix X in your previous analysis, you can re-run the analysis by adding your new contrasts through option -xrestore. Otherwise, you'd have to run a new analysis to obtain all the contrasts including the new ones.
