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

Hi Rick,

Alright, I see ... if you check the "Pos?" box under the colorbar in the main AFNI window, in the Cluster Results window the 4th line from the top ("Alpha -> Cluster Thresh") gives cluster size thresholds that match indeed the values in the clustsim*1sided.1D file saved by 3dttest++ (with the option -Clustsim).

If you leave the option "Pos?" unchecked, instead, the cluster size thresholds reported in the Alpha line of the Cluster Results window match the values in the clustsim*2sided.1D file (or the clustsim*bisided.1D file, the values are often the same).

thanks for checking!

best
giuseppe
