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

For t statistics with microscopically small p values, the convert-to-z-score functions puts in z=13 -- which is a ridiculously large z-score; anything over z=6 has a p value smaller that 2*10^(-9). It never seemed worth the effort to accurately compute the precise z-score corresponding to a large t statistic, since both values are way out in the tails, and if you really believe data is that normally distributed, I have a black swan for sale.
