Hi FreeSurfer experts,

I happen to have a participant whose brain lesion from stroke (hemorrhage) distributed over a wide area. Therefore, the recon-all result is showing a big whole, about half a size of the cortex, on the anterior part of the left hemisphere corresponding to the lesion site.

When I checked the previous mails, it is recommended to edit the WM volume for the whole caused by lesions: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/WhiteMatterEdits_freevi...

But because the size of the lesion is so big, involving more than 100 slides coronally, the process to fill the lesion area by Voxel Edit will be as long as tracing the lesion manually slide by slide. I wonder if you would have other suggestions to correct such a big geometric accuracy.

Please let me know if you need other info. Thank you so much for your help!
