Dear Mingrui and Archana,

Thank you for pointing out this issue.
I ran into the same problem: rendering the images is fine, but when I try to save it, Matlab crashes (i.e., gets stuck being busy forever).
The option to switch from opengl to zbuffer allows me to save the images, but the problem is that the brain is not transparent anymore so the connections cannot be seen when using zbuffer.

I would be happy about any suggestions to resolve this!
Best,
Andreas
