ODV files needed: Collection File and Data File (zipped). Instructions: create a new directory/folder (use no spaces in the directory name). Save both files to the new directory/folder (on a Mac: right click and select "Save link as...", or something similar, depending on your browser), unzip the data file (double clicking on it will usually do it), double click on the collection file. ODV should open automatically (otherwise open the file from ODV). After opening it should look similar to this screenshot.
