1Chemistry::Ring version 0.20 2============================ 3 4The Chemistry::Ring module provides some basic methods for representing a ring. 5A ring is a subclass of molecule, because it has atoms and bonds. Besides that, 6it has some useful geometric methods for finding the centroid and the ring 7plane, and methods for aromaticity detection. 8 9The Chemistry::Ring::Find module implements a breadth-first ring finding 10algorithm, and it can find all rings that contain a given atom or bond, the 11Smallest Set of Smallest Rings (SSSR), or the "almost SSSR", which is an 12unambiguous set of rings for cases such as cubane. 13 14This module is part of the PerlMol project, L<http://www.perlmol.org/>. 15 16CHANGES SINCE VERSION 0.19 17 - Silence some warnings. 18 - Minor changes by Liliana Felix Avila for compatibility with 19 Chemistry::Artificial. 20 21INSTALLATION 22 23To install this module type the following: 24 25 perl Makefile.PL 26 make 27 make test 28 make install 29 30DEPENDENCIES 31 32This module requires these other modules and libraries: 33 Chemistry::Mol 0.24 34 Statistics::Regression 0.15 35 36COPYRIGHT AND LICENSE 37 38Copyright (C) 2009 Ivan Tubert-Brohman <itub@cpan.org> 39 40This library is free software; you can redistribute it and/or modify 41it under the same terms as Perl itself. 42 43
