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

No, 3dFDR does not change the original value at each voxel if it is outside a mask, instead when it is implemented with the FDR algorithm (see page 2 of 3dFDR manual http://afni.nimh.nih.gov/pub/dist/doc/manual/3dFDR.pdf), those voxels are excluded (and not counted for correction in terms of total number of voxels N) from the process.
