Dear Bruce, Dear Bram, Thanks a lot for having a look. Unfortunately the left hemisphere is equally important as the right one for our question of interest. With a lot of patience the recon-all has finished and the result looks surprisingly ok. I have additionally re-run it (recon-all -autorecon2-cp -autorecon3 -s Case) after setting control points to correct errors in the wm.mgz. Some errors were corrected, but not all. Next I would like to correct the surfaces. My questions:
- I know that recon-all is not designed for such a subject. But is there any argument against continuing the analysis now? - What can I do for those errors where the wm.mgz is still false, despite control points? I have uploaded the respective files.

Recon-all is not designed to work on scans with such large lesions. If you are interested, there may be a way to generate a reasonable model of the right hemisphere.
