Hello Bruce,
Thank you very much. I'm guessing I should follow the tutorial for editing aseg; or is there a different tutorial on how to edit and label WM lesions on aseg? One last question, what if it's a combination of WM and GM lesions like cortical stroke that extended into the WM? Should I use the same procedure?
Best, Paul

Hi Paul
if they are WM lesions I think you should edit the aseg and label them as such, then run from there forward. It should propagate the lesions from aseg to wm.mgz, so you shouldn't have to do both Bruce

Hello Bruce, I am interested in this thread because I have encountered similar problems with my stroke patients. How do I solve it? Should I only edit the aseg and assign a label called "Lesion" in the FS LookUpTable? or Should I edit both the wm.mgz and aseg.mgz files? If the former, How do I achieve it? My goal is to make sure that WH and GM surfaces are traced properly. Any help will be appreciated. Thank you.
Best, Paul

yes, control points would mess everything up. It looks like the rest of the surface was generated pretty accurately though - do you need to correct anything?
cheers Bruce

Hi Freesurfer experts,
I am running FS on a patient with a chronic right occipital lobe infarct as part of a larger study. The program does not recognize the area around the lesion as brain matter, and I am wondering how best to treat this situation. I am worried that adding Control Points will incorrectly label the region as white matter. I am attaching some pictures of slices where this is apparent. Thank you so much for your help!
Best,
Mariana
