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

I guess I'm trying to make a shortcut. If I have two sets of briks
that produce individual stats (a ttest, say), you might say it's
probably better to combine the two sets into one statistical
computation (an anova, perhaps).

I'm looking for a quick test (other than a side-by-side visual
comparison) that will tell me if the results of two different ttests
are the same (or rather, where they are both significant). I figured
something along the lines of converting to p values, thresholding, and
multiplying. I don't need a new statistic. I was thinking that was
what the fizt_t2p(t) et al. things were for.
