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

Hi,

After installation, when I start AFNI on WSL2 (Ubuntu 20.04), it gives me the following error: 

Initializing X11 Error: Can't open display: 0.0
++AFNI is detached from terminal


I've launched VcXsrv before starting terminal and I've tried switching to WSL1 too (as advised in other threads).

The output of afni_system_check.py -check_all is following:
