RE: mricron "descriptive statistics" output
An voxel without a drawing/overlay are considered to have a value of zero, those with some overlay are considered to have a value of 1. Therefore, if 90% of the region is marked with a drawing, the fraction would be 0.9.

You may want to consider trying out the more modern MRIcroGL. It will provide similar descriptives:
