nope, I would use Left-non-WM-hypointensities and Right-non-WM-hypointensities

Hello Bruce, Thank you. I looked at the LookUpTable.txt for GM and I couldn't find any. I only found labels for Right Lesion, Left lesion, WM lesions (wmsa and other_wmsa). What does wmsa mean and which of these should I use as GM lesion?
Best, Paul

GM ones are harder and I'm not sure we have a working procedure for them yet. I think we have separate labels for wm and gm lesions - try using them when you edit the aseg. cheers Bruce On Sun, 3 Sep 2017, miracle ozzoude wrote: 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 Sent from my BlackBerry 10 smartphone.

It should propagate the lesions from aseg to wm.mgz, so you shouldn't have to do both Bruce On Sun, 3 Sep 2017, miracle ozzoude wrote: 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.

It looks like the rest of the surface was generated pretty accurately though - do you need to correct anything? cheers Bruce On Wed, 21 Jun 2017, Budge, Mariana wrote: 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!
