Hi Mike
yes, I think it is fixed. Daniel: can you try out dev and see if it fixes this for you? Bruce

That looks very similar in principle to something I posted back in Oct. 2014 (“pial surface crossing white”).
I think some of the subsequent back-and-forth with Bruce and Nick was off the list, so I’ve included the key email (where Bruce diagnosed the problem) below.
Has this been fixed in the forthcoming FS 6.0?
thanks, -MH

ok, I see what's going on. Here is the sequence of calls:
- mris_make_surfaces -noaparc -whiteonly -mgz -T1 brain.finalsurfs
L408_base lh
Makes the white surface *without* using the aparc. Because there are a string of "hypointensity" labels in the aseg, the white surface is frozen in these locations.
- mris_make_surfaces -white NOWRITE -mgz -T1 brain.finalsurfs L408_base
lh
internally recreates the white surface but doesn't save it. The frozen vertices are allowed to move since the aparc *is* used in this call, and the vertices are deemed to be in real cortical regions.
The pial surface then starts from the (inwards deformed but not written to disk) white surface, and then settles inside the white surface that is on disk.
I'm not sure how we settled on this logic. Why recreate the white surface? Why not run with -nowhite -orig_pial white? That way the algorithm uses the white surface that the user can see and things should be consistent

Hi,
I followed the advice, and the White Matter surface looks much better; however, now the pial surface is crossing the white matter surface.
I ran the following: /usr/local/freesurfer/stable5_3_0/bin/recon-all -subjid nmr01002 -autorecon2-wm -autorecon3 -openmp 8
for those at Martinos the new subjid should indicate the new path.
I've attached a screenshot. Thank you in advance for any advice you can give.
Thank You, Dan

Hi Bruce,
Thanks! I'll give it a whirl.

Hi Daniel
the problems isn't that it it's ignoring the wm edits, it is that it starts the orig surface out there, but then retracts to the (same) visible gray/white boundary that it found in the first place. For this type of lesion I think what you should do is also edit those voxels in the aseg.mgz and change them to right-lesion. This should freeze the white surface there I think. If it doesn't, let me know and I'll fix it.
cheers Bruce

can you send us the recon-all.log? I don't see an obvious reason why it wouldn't have worked On Tue, 19 Apr 2016, dgw wrote:
Just to follow up, I have tried several different options with recon-all to get the white matter edits to stick on this participant, and it doesn't seem to be working:
re-editing wm.mgz and running recon-all -autorecon2-wm re-editing wm.mgz and running recon-all -make all
I can't seem to get any appreciable change in the white matter surface. I have attached a screenshot, for an example.
