Split selection

Given an initial selection, Split_selection will create two new selections. One, called 'lo,' will have all the atoms with IDs lower than your input atom (actually input residue's alpha carbon); and the second selection is 'hi,' which contains the atoms with IDs higher than the initial (residue's alpha carbon) atom.
  • The original selection

  • The lower selection

    The lower selection

  • The higher selection

The Code

<source lang="python"> import pymol from pymol import cmd

def get_index_list(s): """ Given an atom selection, return the list of atom IDs in this selection """ return map(lambda x: x.index, cmd.get_model(s).atom)

def get_single_index(s): """ Get the ID of the first alpha carbon in the selection, S """ # assume CA return get_index_list( "n. CA and (br. %s)" % s)[0]

def split_selection(s): """ PARAMS s An atom selection.

RETURNS None

SIDE EFFECTS Creates two new selections, called lo and hi. Lo will have ..→
