External Email - Use Caution        

 
Hello Gonzalo,

If you have not already done so, then I suggest installing the  .deb installer package for 7.3.2 from,

surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/7.3.2/freesurfer_ubuntu18-7.3.2_amd64.deb

- by cd’ing to where you downloaded the above file to on your machine and then running,

$ sudo apt install ./freesurfer_ubuntu18-7.3.2_amd64.deb

Then test the environment with,

$ export FREESURFER_HOME=/usr/local/freesurfer/7.3.2
$ source $FREESURFER_HOME/SetUpFreeSurfer.sh

$ which freeview
$ /usr/local/freesurfer/7.3.2/bin/freeview

… check freeview comes up with an empty window …

$ freeview

… then quit and try viewing an example volume …

$ freeview  $FREESURFER_HOME/subjects/bert/mri/brain.mgz

- R.

Hi:

  I have Ubuntu 18.04.4 LTS and freesurfer release freesurfer-linux-ubuntu18_x86_64-7.3.2-20220804-6354275. When I run freeview, I got the error:

"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, webgl, xcb."

  How can I correct it?

  Sincerely,


Gonzalo Rojas Costa
