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.

Hello -

I have a series of T1w volumes with gadolinium signal present...and I'm having difficulty registering them to an atlas volume (AFNI_18.0.26, auto_warp.py, MNI_T1_2009c+tlrc). Specifically, 3dQwarp seems to interpret the vessels as 'brain,' and wraps them around cortical folds. Is there any principled way to remove the gadolinum signal, while sparing brain?

Thank you,
Pete
