R package (or other software) allowing to save a biological network in GPML format

Question

[lech.kaczmarczyk]

I would like to import a custom made pathway into Pathvisio. It only accepts GPML format. Is there any R package containing a relevant export function that I could use? Cheers, Lech

export to GPML from which format/data ?

Using the R igraph package, export from igraph as GML with write_graph() and import into Cytoscape then use the Cytoscape GPML plugin to export to GPML, or save the graph in dot format then convert to GPML using the Systems Biology Format Converter. Yet another option would be to write a GMPL file yourself since it's an XML format with open specification.
