>> As mentioned in the user guide, the best format supported by NetworKit is METIS adjacency format, my question is: Is there a way to read csv file (or postgres table) directly into this format? If there is not, what is the best way to convert network data from edge list format to METIS?

> Format.EdgeList           Format.EdgeListSpaceZero  Format.GML                Format.KONECT             Format.SNAP

> For example, if your file is a list of edges, i.e. node ids separated by a tab, where the first node has id 0, use this format:

> Also, if you are familiar with Mercurial, I recommend that you work with the latest revision in the „Dev“ branch of NetworKit. There have been important updates that have not yet been released.

> Good luck with the thesis, (and perhaps let us know via the list what kind of problems you are working on)
