∟PyMol Measurement Functions

∟Use Selection Expressions in PyMol

This section provides a tutorial on how to use atom selection expressions in measurement commands directly, instead of pk1, pk2, pk3 and pk4 selection names in PyMol.

PyMol commands supports selection expressions directly, in addition to selection names or default selections.

For example, the following commands creates new measurement selections with atom selection expressions: 

# create distance between atom #2 and #3
distance dis1, id 2, id 3

# create angle formed by atom #3, #4 and #5
angle ang1, id 3, id 4, id 5

# create dihedral angle formed by atom #3, #1, #4 and #5
dihedral dih1, id 3, id 1, id 4, id 5
