the subject.pvc.label.nii.gz will have GM/WM/CSF labels only.
Then the subject.skull.label.nii.gz will have skull, scalp, space and brain labeled.

detailed information can be found here: http://brainsuite.org/processing/surfaceextraction/skull-and-scalp/

well the subject.pvc.label.nii.gz have GM/WM/CSF and combinations of each(partial volume).I’d like to know if one can have the five tissues( GM,WM,CSF,skull and scalp) all together in a label without partial voolume being considered .

To get WM GM CSF, you can use subject.pvc.frac.nii.gz. This file contains tissue fractions, i.e. amount of GM WM CSF at each voxel in the brain. Since at MR resolution, many voxels contain mixture of tissue, so this is a more realistic representation than the crisp segmentation.
If you want information about WM GM CSF Skull and Scalp, you can use this file and subject.skull.label.nii.gz.
