Dear experts,
I recently finished processing a subject for whom I had performed a skull-strip on the brainmask.mgz volume. I decreased the watershed parameter and re-examined the brainmask and the portion of the skull was gone, although some dura was left over. I did a recon-all using the following command as the troubleshooting tutorial suggested to regenerate the surfaces based on the new brainmask.mgz volume:
recon-all -autorecon-pial -subjid <subject name>
However, after the subject finished processing the surfaces were generated/outlined on the dura as well. I tried performing a g-cut command but it did not get rid of the dura. I also had issues with the subcortical segmentation as the ventricles were not completely segmented.
Thank you for your help.
Best,
Arsenije
