S Quirk et al. External respiratory motion: Shape analysis and custom realistic respiratory trace generation. Medical physics 39 (8), 4999-5003.

External respiratory trace generator developed using population data from external motion of cancer patient database. The software can be run in two modes: population and user defined. In population mode the traces are generated entirely based on the population data. In user generated mode some characteristics can be manipulated including amplitude, period, end exhale phase, and variability amount. The traces are saved as csv files so they are easy to use and convert for any purpose. Don't hesitate to contact me if you have any questions.
