thanks Doug. it worked and I got the following result on which I have clarifying questions:
-------------- Voxel Volume is 1 mm^3 Generating list of segmentation ids Found 1 segmentations Computing statistics for each segmentation 0 1 81837 81837 ---------------- 1) I'm assuming that voxel here refers to vertex since I'm submitting the surface data. 2) what does 'found 1 segmentations mean'? 3) the dimension is 81837mm^2, correct?
