KEGG pathway database is a collection of manually drawn pathway maps representing current knowledge on molecular interaction and reaction networks, accompanied with KGML (KEGG pathway xml format) files for automatic computational analyses and modeling of metabolic and signaling networks. In a KGML file the pathway is represented as a graph object with entry elements (gene products, compounds, pathways) as its nodes, and relations between elements as edges. However, in most cases there is a lack of correspondence between static images of pathways and accompanying KGML files, so preprocessing of information contained in a KGML file is needed before it can be used in automatic analysis. Several KGML parsers have been developed recently, both standalone or integrated in different bioinformatics packages.
We introduce KEGGParser (pathway parser/editor), which is based on Matlab biograph class.

Features:
1. Retrieval, parsing and automatic correction for protein-compound-protein interactions, group nodes and binding directions;

2. Pathway graph editing (edge and node manipulations) based on "Graph manipulation" (http://www.mathworks.com/matlabcentral/fileexchange/37475-graph-manipulation);

3. Analysis of parsed pathways can be performed using Matlab built-in graph-based calculations.

Version Published Release Notes
1.9.0.0

1. Minor bugs are fixed.
2. Addition of new pathway to the saved pathway collection
3. Button to delete unconnected nodes.
4. Improved parsing for metabolic pathways (relation attribute based parsing)

1.8.0.0

Recent updates
1. kegg_batch.m updated to communicate with the new REST-style version of KEGG API, thus restoring functionality of "Batch Update" option.

2. parse_KEGG_xml.m updated to allow creation of graphs without edges.

Fixed problem with parsing relations without subtypes. Added automatic correction for protein-compound-protein interactions, group nodes and binding directions.

1.6.0.0

Fixes:
1. Fixed problem with parsing relations without subtypes.
2. Added automatic correction for protein-compound-protein interactions, group nodes and binding directions.

1.5.0.0

I have found a bug, that results in wrong assignment of interaction types. It is fixed. Scilab version of KEGGParser is also included. Works with Scilab 5.4+metanet
