# First three lines represent: (used by rotor.cpp::OBRotorRules # |
| 10 |
# Hybridization pair (atom types around a rotatable bond) # |
| 11 |
# followed by a list of default bond rotation angles (in degrees) # |
| 12 |
# # |
| 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 # |
| 20 |
# # |
| 21 |
# SMARTS rules will be attempted first, then hybridization # |
