Distance measure (DM) calculation. Along each protein, the distance is the maximum difference between start and end positions (startAlab - startAPS, endAlab - endAPS). When the predicted site is contained within the lab site, the differences are both negative and we clamp the maximum difference at 0 (perfect match). Distances along each protein are scaled and combined vectorially to yield the DM.
