These folder contain the filtered and tracked graph objects as .pickle file. The files can easily be opened and transformed into any other file format using the powerful networkx library. The structure of the graph files is as follows. Each file contains one graph that represents the entire timeseries of physarum networks. This graph is basically a union of the graphs at t=1, t=2, ... t=k respectively. These k subgraphs are capture the topology of physarum networks at different times. Their nodes have the form ((x,y),t). Running between the k graphs are the tracking edges that are marked as such with an edge attribute. Thus, if you are interested in studying the graphs at different t, then simple remove all tracking edges and split the graphs according to the time t stored in the nodes. However, if you are interested in looking at the node tracks, then remove all non-tracking edges and compute the connected components, which are the tracks. Networkx provides appropriate facilities for both tasks.
