Supplement 1. Visual Basic source code containing the algorithms described in this paper.

File List <i>All files at once</i> BBridgeCode.zip -- zip file containing Visual Basic executable, source code, and example input file. <i>Individual files</i> BrownianBridgeExecutable.exe – Executable Visual Basic program<br> ProjBrownianBridge.vbp.txt – Source code for Visual Basic program<br> ProjBrownianBridge.vbw.txt – Source code for Visual Basic program<br> FrmBBAnalysis.frm.txt – Source code for Visual Basic program<br> FrmGridExtent.frm.txt – Source code for Visual Basic program<br> FrmOpenFileBB.frm.txt – Source code for Visual Basic program<br> FrmSaveASBrownBridge.txt – Source code for Visual Basic program<br> Mod1DMinimization.bas.txt – Source code for Visual Basic program<br> ModFileManagement.bas.txt – Source code for Visual Basic program<br> ModPublicVariablesBB.bas.txt – Source code for Visual Basic program<br> ExampleInput.txt – Example input file<br> 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 <i>x</i>-coordinate, <i>y</i>-coordinate, and time of each location. The input file should have column headings such as “<i>x</i>-coordinate”, “<i>y</i>-coordinate” and “RunningClock”. An example input data file, ExampleInput.txt, is available from the file list. Output grid is a text file containing <i>x</i> and <i>y</i> coordinates of the grid along with associated probability-of-occurrence at that grid location.
