Chemistry::File::FormulaPattern - Wrapper Chemistry::File class for Formula
patterns
use Chemistry::File::FormulaPattern;
# somehow get a bunch of molecules...
use Chemistry::File::SDF;
my @mols = Chemistry::Mol->read("file.sdf");
# we want molecules with six carbons and 8 or more hydrogens
my $patt = Chemistry::Pattern->new("C6H8-", format => "formula_pattern");
for my $mol (@mols) {
if ($patt->match($mol)) {
print $mol->name, " has a nice formula!\n";
}
}
# a concise way of selecting molecules with grep
my @matches = grep { $patt->match($mol) } @mols;
This is a wrapper class for reading Formula Patterns using the standard
Chemistry::Mol I/O interface. This allows Formula patterns to be used
interchangeably with other pattern languages such as SMARTS in the context of
programs such as mok. All of the real work is done by
Chemistry::FormulaPattern.
This module register the 'formula_pattern' format with
Chemistry::Mol.
Chemistry::Pattern, Chemistry::File, Chemistry::Mol, Chemistry::MacroMol, mok.
