This folder contains the data obtained in 81 wet-lab experiments under identical conditions. Each of the experiments, named motion*, shows a timeseries of the growth of Physarum taking a digital image every 120 seconds. The length and quality of the series differ due to the uncontrollable growth of Physarum. Note the large size of the folder of 266 GB.

A short summary of one experiment is as follows:

1) A rectangular plastic dish is prepared with a sheet of agar and is placed in a light proof box.
2) A small amount of dried P. polycephalum sclerotia crumbs are lined up along the short edge of the dish.
3) After approximately $14$ hours the plasmodium has resuscitated and moved towards the far side of the dish covering a distance of approximately $5$ cm. From this point on network formation sets in.
4) For the next $30$ hours we take a top-view image of the growing plasmodium and the changing network every $120$ s. We stop capturing when the growing front is about to reach the far side of the dish.
5) Given these images showing the characteristic networks of P. polycephalum, we use a software called NEFI to compute a graph representation of the depicted structures [dirnberger2015nefi]. The graphs store precise information of the length and width of the edges as well as the coordinates of the nodes in the plane.
6) Given the resulting sequence of graphs we compute a node tracking encoding the history of every node taking into account the changing topology of the evolving graphs.

CONTETS of the present folder:

motion*

Series of raw images obtained in 81 wet-lab identical experiments. Before the sequences of images can be used with NEFI, suitable subsequences and regions of interest need to be defined. Some series need to be exclude because of unfavorable growth (e.g. Physarum escaping the container).

config_backup

Folder that contains backups for the config files associated with each experiment. The config files store information about the usable subsequences and the actual region of interest. The original config files rest in their respective experiment folders. Note that, depending on your research question, you may need to adapt the region of interest and/or the subsequences!
