I'm not sure what you mean. Nerodes is the number of recursive 1 voxel
erosions.

Does it use the same algorithm as in "mri_binarize -erode Nerodes"

It computes a "trimmed" mean/std in each ROI by excluding the top and
bottom X% intensities.

Does it always exclude the X% intensities, or it uses some outlier detection algorithm to identify maximum X% outliers?
