choose_ligand(parent,
complex_st,
text=None)
|
|
Given a Structure object and a parent window, ask the user to select a
ligand from the complex (if more than one is available).
If no ligands are present, ValueError is raised.
If only one ligand was present, the Ligand instance for it is
returned.
If the user selected a ligand, the Ligand instance for that ligand is
returned (See schrodinger.structutils.analyze.Ligand)
If the user cancelled the dialog, None is returned.
- Parameters:
parent (QWidget) - Parent for the dialog window.complex_st (structure.Structure object) - Receptor/ligand complex structure.text (str) - Label to show at the top of the ligands table.
