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

>> #1 what is the significance of the first colum ?

The first column is the voxel index number.

>> #2 Why in the second study p,q values do not change at all?

As the p-value listed in the 2nd study does not change much, the algorithm simply renders the same q value, thus the same z-score. Go to page 2 of 3dFDR manual, you will see how the algorithm works.
