This script-kit is a collection of small script to be able to precisely to put a molecule (like a dye) where you want in relation to a protein.

You can also create rotational states of a domain or simulate a dye freedom.

It simply makes the PyMOL TTT matrixes, in a easy and user friendly way. The calls to the functions available in PyMOL, takes care of all the conversion of input and such.

If you are interested in this, you might also want to check out the PyMOL Chempy module that is included in PyMOL. It provides handy vector and matrix functions.

Functions available in PyMOL

  • rotateline(Pos1,Pos2,degangle,molecule):
    "Pos1->Pos2" define a line whereabout "molecule" will be rotated "degangle" degrees
    rotateline Pos1=P513C_CA, Pos2=P513C_CB, degangle=5, molecule=Atto590
    rotateline Pos1=dyeatom87, Pos2=dyeatom85, degangle=10, ..→
