KCOMBU: for matching chemical structure by the build-up algorithm

KCOMBU stands for K(ch)emical structure COMparison using the BUild-up algorithm.

What is MCS (Maximum Common Substructure) ?
The program package KCOMBU contains following programs:
pkcombu: Pairwise MCS Comparison of Chemical Structure
fkcombu: Flexible Transformation of 3D Conformer by Pairwise MCS Comparison
lkcombu: Library Search using Pairwise MCS Comparison
dkcombu: Fast Library Search using Atom Pair Descriptor and Pairwise MCS Comparison
ckcombu: Conversion of Chemical File Format and Generation of 2D coordinate.

The program KCOMBU is used both in the LigandBox server and the HOMCOS server.
