-"""This script loads a segmented cf graph in the gt format, iterates
-on all of the edges and cost functions and generates the trajectories
-as done in MATLAB. Segments (nodes) have a new vertex property called
-"traj_prop" that holds the trajectory ID that that segment belongs to. The
-output is either an expanded JSON file and/or an edgelist file with
-all of the trajectories.

-Inputs:
-the gt segmented cf graph
-Output:
-trajectories.json that contains all of the trajectories
+"""This script loads the graph of segments, with cost functions and
+identifies trajectories.
+
+Inputs: the graph of segments produced by Graph-tool (gt or graphml
+format).  Output: trajectories as lists of segments and as lists of
+instantaneous eddies, in JSon files.
