Dear AFNI users-
We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

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,

Hi,
In my project, I have found some voxel-clusters which have shown significant difference between Group A and Group B (at the p-value level about 0.01 in those voxel clusters). But after multiple comparison (e.g. FDR) for all 67000 voxels , the p-value of those voxel-clusters are more than 0.05.
I try to use 3dttest++ to do the cluster-level (e.g define 69 voxels as a clusters) multiple c
