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

Hello everyone,

After conducting a single subject analysis with surface data using 3dDeconvolve I found that the p and q values were very similar. I then used 3dcalc to create new contrasts based on the 3dDeconvolve results and recalculated the FDR curves with 3drefit. To my surprise I found that the corrected q values were now smaller than p. I am aware that this is theoretically possible with FDR but I'm not sure how verify if it is correct or if I have made a mistake somewhere.
