Dear Freesurfers,
I have a question on manual white matter edits:
I have cases where a considerable amount of gray matter is classified
as white in my wm.mgz and therefore the original surface (green) is
not accurate but then that is fixed in the next steps and the wm
surface (yellow) is accurate in 90% of the areas but not accurate in
other 10% .
Now my questions are:
1-Will I get accurate results if I do the edits (erasing
misclassified white matter in wm.mgz) to my white matter mask only in
those 10% areas that the wm surface is not accurate or should I
correct the wm.mgz 'every where' no matter what?
2- Will you necessarily get more accurate results by editing your
wm.mgz where pixels are classified as white by mistake BUT your final
white matter surface is accurate?
3-How much on average takes you to do the manual white matter edits
for each of your subjects?!
Thank you,
Nasim
