1Chemistry::Ring version 0.19 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 0.18 17 - Fixed memory leak. 18 - Added 'ring/rings' attribute to molecule on aromatize_mol. 19 20INSTALLATION 21 22To install this module type the following: 23 24 perl Makefile.PL 25 make 26 make test 27 make install 28 29DEPENDENCIES 30 31This module requires these other modules and libraries: 32 Chemistry::Mol 0.24 33 Statistics::Regression 0.15 34 35COPYRIGHT AND LICENSE 36 37Copyright (C) 2005 Ivan Tubert-Brohman <itub@cpan.org> 38 39This library is free software; you can redistribute it and/or modify 40it under the same terms as Perl itself. 41 42
