In this example, we read a protein from a PDB file and then add a layer of atom::Fragments below the chain.
14 hchain = IMP.atom.get_by_type(ep, IMP.atom.CHAIN_TYPE)[0]
16 children = hchain.get_children()
23 for x
in children[:10]])
24 for c
in children[:10]:
25 hchain.remove_child(c)
30 for x
in children[10:20]])
31 for c
in children[10:20]:
32 hchain.remove_child(c)
36 for c
in children[20:]:
37 hchain.remove_child(c)
