Did you know... SelInside selInside selects all atoms of a certain type that are located within the bounding box defined by some selection. See examples. Usage # find all atoms inside the box spanned by (0,0,0) and (10,10,10) # for the example PDB, 1hpv fetch 1hpv pseudoatom b1, pos=[0,0,0] pseudoatom b2, pos=[10,10,10] selInside b1 or b2 The Code <source lang="python"> import pymol from pymol import cmd, stored from random import randint def selInside(bounding_object, target="*", radius=None): """ Selects all atoms of a given target type inside some selection that acts like a bounding box.
