Re: [Freesurfer] freeview display problem

Is there any error message on the terminal? What happens if you run “glxgears” 
command? Does it run?

Ok, you should try updating your graphics card driver. There is also chance 
that your graphics card is broken. Unfortunately we are not able to diagnose 
that for you. Sorry.

The color should be red, blue and green. It is your graphics card or graphics 
driver issue.

Re: [Freesurfer] freeview display problem

[Ruopeng Wang]

This sounds very likely a video card/driver issue. Would it be possible for you 
any other program that uses OpenGL/vtk, such as 3D slicer, Paraview? How does 
glxgears command show?

Re: [Freesurfer] freeview display problem

[Ramtilak Gattu]

Nope they dont look normal they are being displayed in some other colors like 
heat is showing up as blue , jet as green etc. Even when the surfaces are 
loaded up the color of the surfaces doesnt look right. when the surface yellow 
is chosen are red it is being displayed as blue.

Re: [Freesurfer] freeview display problem

[Ruopeng Wang]

So it happens with freeview all the time? Freeview uses openGL as backend for 
rendering, which I believe is not the case for fslview. Would it be possible 
for you to update your graphics card driver?

Re: [Freesurfer] freeview display problem

[Ruopeng Wang]

That’s indeed strange. I wonder if it is a graphics card issue. Does the blue 
tone appear all the time? on any volume?

Is there any other layer loaded? It looks like there is at least another 
overlay on top of the volume layer?

Best,
