Re: [Freesurfer] Transparency surface

Hi,

Is there a way to see both side of the activation with a brain which looks like the pial ? Without inflated maybe I'm not really familiar with tksurfer. So far I used tksurfer fsaverage6 lh inflated by default.

Thank you.

Hi Arnaud

can you in general cc the list on these questions so that others can answer.

What you are trying to do is what the inflated surface is designed for. I don't think the transparency thing would work - it would just be confusing

Hi Bruce,

I added two pictures so you can see what I referred to. When I display the main surface, I'm able to see my activation. But when using the pial surface, it's hard to see the activation. I thought that if I could change the transparency of the surface, I will be able to see the other side (i.e., hidden in the sulci) of the activation (as shown in the main surface).

Thank you for your answer.

  why would transparency help? You should be able to view the overlay

on any surface without transparency (the overlay defines the colors displayed on the surface). Can you explain further why the normal display in tksurfer doesn't do what you want?

  cheers

        Dear Freesurfer experts,
        Using tksurfer I open an inflated surface and I display the

pial surface. Then I load an overlay but I'm not able to see it correctly. Is it possible to put a transparency/opacity value for the surface so I can see better my overlay ?

        Thank you for your help
