NAME

Chemistry::File::MidasPattern - Wrapper Chemistry::File class for Midas patterns

SYNOPSIS

use Chemistry::File::MidasPattern;
use Chemistry::File::PDB;

# read a molecule
my $mol = Chemistry::MacroMol->read("test.pdb");

# define a pattern matching carbons alpha and beta
# in all valine residues
my $str  = ':VAL@CA,CB';
my $patt = Chemistry::MidasPattern->parse($str, format => 'midas');
# Chemistry::Mol->parse($str, format => 'midas') also works

# apply the pattern to the molecule
$patt->match($mol);

# extract the results
for my $atom ($patt->atom_map) {
    printf "%s\t%s\n",  $atom->attr("pdb/residue_name"), $atom->name;
}
printf "FOUND %d atoms\n", scalar($patt->atom_map);

DESCRIPTION

This is a wrapper class for reading Midas Patterns using the standard Chemistry::Mol I/O interface. This allows Midas 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::MidasPattern.

This module register the 'midas' format with Chemistry::Mol.
