NeuroData's Graph DataBase

Biologically Derived Graphs

Thanks to all who provided the raw data from which we derived these graphs. Every graph is annotated with a source attribute that denotes its origin.

Graphs are provided by default in graphML format. This is the only format that supports iterable attributes.
