13 # Later lines should specify: #

14 # * A SMARTS pattern for the rotor rule #

15 # * A set of 4 "reference atoms" (as integers, numbered from 1 #

16 # in the specified SMARTS pattern #
|
|
|
17 # * At least one torsion value (in degrees) #
|
|

18 # * Optionally ending with "Delta" and a delta value #
|
|
|
19 # (i.e., the resolution of a dihedral step #
