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

Are you talking about running a two-sample t-test with 3dttest on brain volume data or something else? What kind of data are you trying to threshold, individual subject data, or each group's average?

> how I might contrast these two now thresholded conditions.

I have the same confusion with your 1st question: not clear about your intention and context.
