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 AFNI Wizards!

Apologies if this question has been asked (I did try a quick search):

I am attempting to perform some basic probabilistic tractography with 3dTrackID. I know for 3dDWItoDT, the gradient vectors file should omit the G0 line. For 3dDWUncert, should the gradient vectors file (-grad option) *also* omit the G0 line, or should that be included for this program?

Thank you in advance!
