Surface missing part.
I was recently confronted to the problem that with some overlay, some part of the surface were missing. 
Do you know why that is?
I attached an example image of that problem.
Thanks.

RE: Surface missing part.
The nifti file looks good. I'm concerning about the surface file (*.nv). Could you please tell me if you have modified the original template? And Could you please try any other template files (e.g. BrainMesh_ICBM152_smoothed.nv)?

Best,
Mingrui

RE: Surface missing part.
Hello, 

i did not modify anything from your toolbox, template nor scripts.
Here is the result with the template you suggested, same result.

RE: Surface missing part.
Hi, I found that the issue is because there are 'NaN' value in the volume. I modified the main program to transfer the 'NaN' to zero. Could you please replace your file with the attached one?

RE: Surface missing part.
This new version solved my problems, NaN were indeed the problem.
Thanks a lot!
