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.

Hi Antonella,
what format are the attachments in? They don't have an extension Bruce On Wed, 13 Jul 2011, Antonella Kis wrote:
Hi Bruce,
Sorry to bother you again. I am doing my corrections for the white matter and
I have few slides where I am not sure what should I do. On the slice no. 82 do I need to
fill/edit voxels on the right hemisphere area where the white surface
(yellow line) does not follow the surface of the brain, but in fact cuts into it 9the black area). Is
this a geometric inaccuracy caused by a lesion where white matter has been
marked as non-white matter? I also attached the next slice no. 81 to see how things will change.
Thank you very much for your help! Antonella
