[PyMOL] rmsd calculation of homologous structures

2007-01-03 Thread Marcela NUNEZ
Hello everybody! I would like to calculate the backbone atoms rmsd of homologous structures (more than two structures at the time), selecting for each one the structured region. Command as fit, rms, pair_fit do it only for pair of structures. Does Pymol has the possibility to do rmksd calculati

Jamaine, That is the percentage of structures with that particular rotamer out of the population sampled (either the backbone bin or for the residue type as a whole). PyMOL presents the rotamers in order of decreasing prevalence. Cheers, Warren -- DeLano Scientific LLC Subscriber Support Ser

[PyMOL] Kabsch & CE Align

Howdy, Just a quick note to those who used my implementation of the Kabsch algorithm for alignments: I have uploaded another version to the wiki http://www.pymolwiki.org/index.php/Kabsch that uses, what I consider, an elegant solution to the problem --- SVD. Also, the new code fixes a small
