[PyMOL] Malformed Selection Error when Measuring Dihedral Angle with Measurement Wizard

[Doug R. <re...@ny...>]

Searched the archive could find anyone else having this problem.

I am unable to use the measurement wizard to measure dihedral angles
using MacPyMOL Education version 1.3.

Opening the wizard and clicking on the four atoms produces the
following output...

You clicked /1f5a//A/PHE`410/CG
 Selector: selection "sele" defined with 1 atoms.
 You clicked /1f5a//A/PHE`410/CB
 You clicked /1f5a//A/PHE`410/CA
 You clicked /1f5a//A/PHE`410/N
Selector-Error: Malformed selection.
( ( v. and + ( pk1 ) ) )<--

I am able to use the wizard to measure bonds, angles, and neighbors
fine; only the dihedral feature is broken.

Also doing a...

get_dihedral /1f5a//A/PHE`410/CG, /1f5a//A/PHE`410/CB,
/1f5a//A/PHE`410/CA, /1f5a//A/PHE`410/N

produces the correct output and result.
