Dear Eli,
I have looked at your data.
Due to the fact that the white matter does have intensity well below 110 in the
large portion of white matter area under your problematic spot, I think that
instead of editing wm.mgz the better way in your case would be to add some
control points to the white matter surrounding region
112,49,128.
Btw, it seems that the white matter has generally very inhomogeneus signal
intensity. Does not the image originate from the subjects with some kind of
severe pathology of white matter?
What is the large hypointense spot centered at 102,64,126? This causes large
hole in wm.mgz But there are other hypointensities, for example at 96,77,151.
Does not your problematic spot correspond to some pathology?
Regards,
Antonin
Bruce,
Main problem area that I can see is at coordinates [104,42,124].My first
attempt, I don't think I had the recon editing box checked when
I was editing the white matter, but I used a brush value of 255. My
second attempt I painted over the same voxels but with the recon editing
box checked.
Both times, after saving wm.mgz I ran the following command:
"recon-all -autorecon2-wm -autorecon3 -subjid my_subject -sd `pwd`"
Only thing different from the guide is I specify a different subject
directory.
Below are download links for the important files, let me know if you
would like to look at anything else. If you look at wm.mgz along with
the rh.white, you can see the surface doesn't appear to acknowledge my
edit.
