Export graph structure

The following exports consider only the graph structure, and can thus be applied to all types of graph in GINsim.

The graph structure can be exported for use in dedicated graph visualization software, which can handle some graphs considered as too large for viewing in GINsim directly. These exports only consider the graph structure (graphical attributes are lost). The following formats are supported:

Graphviz: Files in the DOT language can be opened using the graph visualization software Graphviz (www.graphviz.org).
BioLayout: Biolayout (see www.biolayout.org), is a graph visualization software focussing on biological networks.
Cytoscape: Cytoscape (see www.cytoscape.org), is also used for the analysis of biological networks. While GINsim can export regulatory graphs for cytoscape, this format is not yet available for other types of graphs.
