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,

Im trying to compare FC of 3 groups using 3dVMV. I tried using this glfLabel below for the F-test, but get the following error: Error in glfRes[[ii]]$Df : $ operator is invalid for atomic vectors.

Heres a portion of my script. Could you let me know where the error is?

Thank you.
