Hey all,

Problem: I am getting white matter ‘holes’ of varying sizes on the wm.mgz

I’ve uploaded 6 images to show an example of such a hole that was created. It is the same wm hole from all 3 views shown in brainmask.mgz and wm.mgz.

The album with all 6 images can be found at photobucket.com/FS51

Background:

The hole appears within the first or second recon-all (after edits made)

They are appearing in multiple subjects

If they do appear in a subject - it is usually between 2-3 per volume

I am using FS 5.1 on a mac (recon on a linux)

I am performing pial/wm/cp edits

I was curious if anyone had ever run into this error and a solution for avoiding it in the future.

Thanks in advance for the help!
