Description

BrownianBridgeExeecutable.exe calculates the utilization distribution (i.e., probability function) based on temporally explicit location data. Algorithms are described in the original paper. The user loads a location file containing tab-delimited columns representing the x-coordinate, y-coordinate, and time of each location. The input file should have column headings such as “x-coordinate”, “y-coordinate” and “RunningClock”.  An example input data file, ExampleInput.txt, is available from the file list. Output grid is a text file containing x and y coordinates of the grid along with associated probability-of-occurrence at that grid location.
