External Email - Use Caution

 

It would be good to know what version of Ubuntu you are running in WSL.   You can see that in the Ubuntu linux terminal window with the command below, and you should see something like the following ...

$ cat /etc/os-release

PRETTY_NAME="Ubuntu 22.04.5 LTS"

NAME="Ubuntu"

VERSION_ID="22.04"

VERSION="22.04.5 LTS (Jammy Jellyfish)"

VERSION_CODENAME=jammy

ID=ubuntu

ID_LIKE=debian

HOME_URL="https://www.ubuntu.com/"

SUPPORT_URL="https://help.ubuntu.com/"

BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"

PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"

UBUNTU_CODENAME=jammy

- which in this case indicates Ubuntu 22.

I would also check you used the Ubuntu 22 .dev installer package from,

https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/7.4.1/freesurfer_ubun... - and installed it from wherever you downloaded it to on the Ubuntu system with the command,

$ sudo apt install ./freesurfer_ubuntu22-7.4.1_amd64.deb

If you didn't use that installer, then the system may be missing xcb related files it needs to run Qt, etc.

If you got that Qt error even after the freesurfer .deb package install completed with no errors, then you could try the commands,

$ xhost +local:

$ sudo apt-get install --reinstall libxcb-xinerama0

Please note you need a license.txt file for freeview to find.  You can put that in your $HOME directory on linux and set the environment variable FS_LICENSE to point to it

$ export FS_LICENSE=$HOME/license.txt

$ head -1 $FS_LICENSE

you@somewhere.com    <-----  email address you used to reigster via the form,

Then try running freeview again (with no arguments to see if it can open an empty window).  $ freeview

- R.

Just re-upping this message in case anyone has any ideas. :)

Hi all,

I've successfully downloaded Freesurfer version 7.4 and can run its commands, with the exception of Freeview. I downloaded and installed Xming, like the FreeSurfer instructions tell you (https://freesurfer.net/fswiki/FS7_wsl_ubuntu), but this does not seem to work, either. I am using Ubuntu on a Windows computer. I get the following error when I run the freeview command :

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

Aborted

Best,

John
