Dear PyMol users! In this topic I'd like to discuss different algorithms of the structure superimposition included in PyMol. First of all I've already noticed that some of such algorithms like CE or TMalign (part of the PSICO) have been already included in PyMol. It's known that such algoritms mainly based on the comparison of the RMSD between examined structures. Besides there are some more sophisticated algorithms for the structure comparison one of which is the VOROLIGN. http://bioinformatics.oxfordjournals.org/content/23/2/e205.abstract This method based on the comparison of the Voronoi contacts of the structures. At this time its very intresting for me if it's possible to visualise such Voronoi contacts in the Pymol as well as perform comparison of them by means of PyMol. Finally are there any other methods for comparison of the protein shapes in PyMol based not only on RMSD measurements? James |
