BioGranat is a molecular biology graph visualisation and analysis tool developed in collaboration by Hochschule Hannover and King's College London. It is based on the Java OSGi bundle architecture and currently provides a graphical user interface, input and output routines for various graph file formats, a facility to use the JUNG library, 2D graph layout routines, 3D visualisation of graphs, JAVA scripting and graph analysis algorithms. Further developments address graphics export (jpeg, vector formats), generation of random graphs and the import of biological meta-information. Biogranat can be used to integrate and analyse large-scale gene networks. BioGranat is available as Open Source Software.


BioGranat is available via sourceforge.

BioGranat tools

BioGranat-RGA and BioGranat-IG are tools to identify subnetworks that underlie diseases.

BioGranat-RGA has been developed to find the largest subnetwork that contains as many as possible genes from a given ranked list of genes. This ranked list can for example be derived from GWAS results using methods published by Lehne et al. in PLoS ONE. 2011, 6(6): e20133.

BioGranat-IG used for finding the smallest subnetwork that represents all or most individuals; the input data is usually a biological network and lists of genes carrying sequence variants in indivduals whose exomes have been sequenced.
