Hi, Sebastian
I think you are right: the final wm surface not only considers wm.mgz and filled.mgz, but the brain.finalsurf.mgz as well. Even though I deleted these voxels with low intensity values in the wm.mgz, the lump at the precentral gyrus still show in the final wm surface. I assume this is due to the high variations of the subjects in this area, causing high intensity values in brain.finalsurf.mgz in these regions.
Also, loading wm.mgz as a segmentation mask works for detecting the voxels with low values. Adjusting only the brightness and contrast seems not enough (see the attached file).
Thank you! Leon

Is there any option in tkmedit that can show volume images with different color schemes such as red-yellow or blue, green? I found the option very helpful in detecting unwanted voxels with low intensity values when I am working on the data in FSL.
The best workaround is to use Ctrl-b to open the brightness contrast dialog and set brightness to 0 and contrast to 30 (both sliders to the right), that way even values of 1 can be seen (to some degree).

Hi Leon,
if I recall correctly the wm surface is looking at intensity gradients in the brain.finalsurfs.mgz (I think). So please have a look at that file and see whether you have some weird issues in that file. The orig surface is created from the wm.mgz and so will reflect edit you made there. BTW I think the filled is created from wm.mgz, so I guess it is guaranteed to match the orig surface… I do wonder why your wm.mgz shows so much structure, as I am under the impression the wm.mgz should basically be of the wm voxel value (I am wondering about the basal ganglia /caudate intensity I guess)

Hi, FreeSurfer experts
I am posting it here again since I still have not had the issue solved. Basically, I find that white matter surface does not follow the wm.mgz file (see the attached files). It is strange that such a problem is only located at the precentral gyrus. I checked the white matter original surface and the inflated surface and they look fine. I also went through wm.mgz slice by slice to see if there is abrupt gradient between slices and it doe not seem to have that either. I also checked the orig.nofix with defects_label overlaied as suggested by Bruce and I do not see red marks close to the region (see attached file).

Are you in any case building a surface for an average subject? In that case it would be better to reconstruct all input individuals and create an averaged surface from those. A lot of NHP people would be happy if a good averaged free surfer monkey would exist (that would mean that you have to build your own template out of all the individual surfaces though).
Also, loading wm.mgz as a segmentation mask works for detecting the voxels with low values. Adjusting only the brightness and contrast seems not enough (see the attached file).
Well in my laptops screen it works well enough. But this is really irrelevant as the orig surface does not include this bit of cortex, so the value of 1 does not hurt there…

Hi, Sebastian
Thank you very much for your information. It is very helpful.
Yes, my intention is to build a surface template based on my subjects for surface-based analyses. As i am fairly new to FreeSurfer, here is my original plan and correct me if I am not heading to the correct direction:
1) Using non-linear registration approach (FNIRT in FSL) to generate a volume-based template first. 2) generate a surface based on this volume-based template 3) register all the subject's individual surface to this template for a surface-based template, based on the instructions in FreeSurfer Wiki.
I checked FreeSurfer documents on how to generate a surface-based template. It seems that it starts from a random individual and do the step(3). However, the reasons for me wanting to start from a volume-based template (step1 and step2) are that having a volume-based template that corresponds to a surface-based template can be helpful if in the future I need to do both volume- and surface- based analyses and need to transfer ROIs between them.
Correct me if my ideas are problematic since I am new to surface-based analyses.
Many thanks Leon
