# SMARTS patterns for atom typing (used by typer.cpp:OBAtomTyper) # |
| 10 |
# # |
| 11 |
# INTHYB: used to assign the internal hybridization values for atoms # |
| 12 |
# IMPVAL: used to assign the implicit valence of an atom # |
| 13 |
# EXTTYP: used to assign the external type of an atom for translation to # |
| 14 |
# package specific types (i.e. Sybyl Mol2) # |
| 15 |
# (these should correspond to INT type names in types.txt too.) # |
| 16 |
# # |
| 17 |
# The LAST PATTERN MATCHED is used to assign values with the corresponding # |
| 18 |
# INTHYB, IMPVAL, and EXTTYP values. Additions to this file should be placed # |
| 19 |
# in the EXTRA DEFINITIONS section (to separate from original patterns.) # |
