Detailed Description

Programmable Atom Typer.

Deprecated:

This code is currently not used by the Open Babel library. Instead, OBAtomTyper and OBAromaticTyper are used. Unless there is interest in retaining this independent class, it will be removed in the future.

Patty stands for programmable atom typer. The patty class was kindly donated by W. Patrick Walters. The patty class provides a more flexible means for atom typing than the OBAtomTyper. The behavior of patty is similar to the OBAtomTyper in that rules apply only to the first atom in the SMARTS pattern. The patty class can read any free format ASCII file which contains SMARTS patterns associated with user defined atom type. The following is an example of a valid patty rule

O=C hbacceptor

The following is a code sample that demonstrates the use of patty class:

OBMol mol;

string rulefile = "rules.txt";
patty p;
p.read_rules(p);
vector<string> type;
p.assign_types(mol,type);
for (int i = 1;i <= mol.NumAtoms();++i)
   cout << "atom number " << i << " was given a type " << type[i] << endl;

The array indices in the vector<string> into which the result values are placed match the corresponding atom numbers. Since atoms are numbered beginning from one, the first element in the vector<string> is empty, and the values are placed in [1...mol.NumAtoms()].
