Did you know... Kabsch Note: PyMOL has built-in commands to do RMSD fitting. This script is typically not needed. In particular, optAlign (sele1), (sele2) is identical to fit (sele1), (sele2), matchmaker=-1. See also: fit, align. Type Python Script Download Author(s) Jason Vertrees License GPL Intro The Kabsch algorithm uses linear and vector algebra to find the optimal rotation and translation of two sets of points in N-dimensional space as to minimize the RMSD between them. The following program is a Python implementation of the Kabsch algorithm. This program when called will align the two selections, optimally, convert the proteins in the selection to ribbons and change the color of the selections to show the matched alignments. WHAT THIS DOESN'T DO: This program does NOT provide a pairwise alignment of two structures from scratch. You have to tell it what the equivalent ..→
