Webb1 jan. 2005 · However, since the LG-score is calculated based on the Kabsch rotation matrix ( 11) that was defined for minimizing the RMSD rather than maximizing the LG-score, this mismatch in the alignment optimization can slow down the convergence of the iteration procedure and reduce the efficiency of these algorithms. WebbRemaining limitations of algorithm and/or this implementation: The Kabsch algorithm is also known as 'partial' Procrustes superimposition (as opposed to full PS) as although there is translation and rotation, there is no scaling.
