Hi Clara
can you send us the wm.mgz and tell us exactly what you did to make it crash?

Dear FreeSurfer experts,
since last week I have the problem that FS (5.3.0) crashes when I try to save changes to the wm.mgz. It closes immediately and the wm.mgz is deleted. I can always restore it by renaming the temporary file (wm.mgz~) but it obviously doen't save any changes.
I've tried different computers (same FS version) and on some it works and on some the same problem occurs. I just tried it on the 6.0.0beta version and it saved like a charm. I would rather, however, keep editing my data with the same version. Here is the error message I get in the terminal:

Any idea what it means by Segmentation Violation and how I can fix it?? Cheers and thanks in advance! Clara Kühn
