HI José
the cerebellum scan quality can be hugely variable due to its intrinsic structure (tiny, almost fractal folia) and distance from isocenter. If you upload the subject we will take a look, or send a snapshot. Sometimes if the cerebellum is too dark in the norm.mgz you can add a control point and recreate the using the -canorm-usecps flag

Dear Freesurfer,
I have been doing some MRI segmentations using the "mri2mesh" command (which does "recon all"). However, I noticed the cerebellum segmentation is not correctly done. It considers the cerebellum as white matter but it also has grey matter. Is there a way to make a more precise segmentation of the cerebellum?
