The test data files collected using the ODiSI software can be replayed from within the same 
software. When in Play Back mode, the measurement data can be viewed with the same plot 
visualizations as the live data. Furthermore, measurement data can be still be streamed using 
OMSP  when  in  Play  Back  mode.  Note  that  the  sensor  properties  and  the  test  file  saving 
actions are no longer available in Play Back mode. 

Browse for a test data file from the menu bar using 

“Tools → Play Back Test Data”. Navigate 

to the test file and click Open.
