I inadvertently omitted the lesion mask pattern [0 1] when running SAMSEG, and while it ran to completion, there were fewer voxels present in the lesion mask (both at thresh 0.3) when I re-ran SAMSEG using the LMP.   The SAMSEG run included a T1 and a co-registered T2-FLAIR image. I am curious as to what the software defaults to in the absence of the --lesion-mask-pattern information.
