yes, the brainmask would be fine. The wm.mgz is to diagnose what went
wrong, but the brainmask tells you whether it is right or not

Hi Bruce,
Thanks again for helping so much. But how about the example in the tutorial
* FsTutorial/WhiteMatterEdits.
I was following the example in how to fill the cutting into for yellow line.
There is mentioned only to open the brainmask and wm.mgz and switching/checking
between the two
volumes. Will be this OK?
Many thanks,
Antonella

Hi Antonella,
you can't tell whether it is correct from overlaying it on the wm.mgz. You need
to look at it over the MRI itself (either the norm.mgz or the orig.mgz) and see
if you would
have drawn it in the same place. The place where the yellow line doesn't follow
the voxel surface is where a topological defect was corrected. It will be
topologically
correct, but possibly not geometrically so.
