HVS Image Water 2020™ file format
HVS Image file structure...
Data files of HVS Image's WATER 2020™ (formerly WATER FOR WINDOWS™) software hold path data of a single trial or session, sampled at a constant interval. The interval should be set to 0.1s (sampling switch on tracker set to SLOW) if the data is later to be imported into Wintrack. HVS files contain no event data. Wintrack expects HVS Image files to have the extension .HVS. Older versions of the software used .DRY and .WET as file name extensions.

Reading HVS data...
The Open Case Document command recognizes new and older HVS Image files automatically. HVS data is expected to be sampled at an interval of 0.1 s (sampling switch on tracker set to SLOW). But Wintrack allows you to specify a different sampling interval to resample data during import. You can also specify an averaging frame for smoothing of the imported data. HVS Image files provide goal position information which Wintrack uses to determine in which quadrant the goal is located. However, exact platform coordinates are not imported, they must be specified for each quadrant using the Arena Properties command. The files are, however, not aware of setup versions which can be applied to case documents when working with custom setup files in Wintrack. Therefore, Wintrack may automatically activate the Case Properties command after loading a HVS image file so you can specify a setup version manually.
You might want to combine the imported trial files into case documents: you can do this using the Append to file option of the Save Case Document As command. As an alternative, you may use Windows™ NotePad (or any other word processing program that can handle plain text files) to write a list of HVS file names. The Open Case Document command will recognize such lists automatically, import the listed HVS files and combine them into a single case document. As you write lists of HVS file names, please respect the following rules:
- Place each file name on a new line by pressing Enter after typing the name.
- Do not include empty lines in front, between or behind the file names.
- The HVS files need to be in the same directory as the file list you prepare.
- If there are missing trial files, place a white space followed by a minus sign on the corresponding line in the list. Wintrack will insert an empty trial for it.
