What are .xws files and how can I view them?
These are short text files that point to specific locations within the records with which they are associated. You can view the same locations using, for example, the PhysioBank ATM. If you haven’t set up a browser helper application for viewing .xws files, you can read them as text and copy the database, record, and annotator into the PhysioBank ATM, then navigate to the location of interest. You can set up WAVE (actually, wavescript) as a helper application for your browser so that when you click on a .xws file, WAVE will open the associated record at the specified location using its built-in HTTP client code (this is much faster and more flexible than using the PhysioNet ATM). See Controlling WAVE from a web browser in the WAVE User’s Guide for details.
