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

Thanks for the follow-up, Nic! I was wondering how 3dWilcoxon performed in dealing with outliers in your case. I'm glad that it worked well for you.

Under what circumstance are you running 3dMann-Whitney for group comparison? Outliers or something else? Could you elaborate a little about the details?
