# SMARTS Patterns are used by finger3.cpp:PatternFP                          #
# Format of each line is a SMARTS pattern, then optionally                   #
#   followed by a tab character and a pattern number and/or description      #
#   (everything after the tab will be ignored by the code)                   #
# A file of this format needs the same first line as this one.               #
# An alternative format, as in SMARTS_InteLigand.txt, can also be used       #
#                                                                            #
#  INCOMPLETE!! Really only useful to test the fingerprint FP3               #
