Did you know... Average b =average_b.py= calculate the average B-factor of a selection. usage copy code to text file and save as average_b.py type "run average_b.py" in PyMOL then type "average_b (selection)" author Gregor Hagelueken code from pymol import cmd,stored def average_b(selection): stored.tempfactor = 0 stored.atomnumber = 0 cmd.iterate(selection, "stored.tempfactor = stored.tempfactor + b") cmd.iterate(selection, "stored.atomnumber = stored.atomnumber + 1") print("Your selection: %s" % selection) print("sum of B factors: %s" % stored.tempfactor) print("number of atoms: %s" % stored.atomnumber) averagetempfactor = stored.tempfactor / stored.atomnumber print("average B of '%s': %s" % (selection, averagetempfactor)) cmd.extend("average_b", average_b)
