Hello FreeSurfer Developers and Community,

 

Hope your day has been going well and happy new year!

 

I'm attempting to visualise FreeSurfer outputs using freeview, as described on the “Introduction to Freesurfer Output” tutorial, under the “Viewing Volumes with Freeview” section (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/OutputData_freeview ). The viewer launches fine and seems to load everything, but instead of showing any output it simply shows a black screen in the middle (screenshot attached). There is no error outputted in the command line either. The viewer seems to work fine otherwise, and I have completed the Xming X-server setup as described here: MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/FSL_wsl_xming .

 

I've searched the archives and GitHub issues and cannot find a similar error. I would appreciate any feedback on how to troubleshoot this issue.

Thank you very much for your understanding and help!
