Using Nuitrack on single frame files (ppm, pgm)

I was wondering if there is anyway to use Nuitrack with recorded kinect data that is not in oni format. Is it possible to use the Nuitrack SDK with frame image files such as .ppm or .pgm if I have access to all of the camera parameters and meta data? Specifically I am wondering if I can take the data in the Berkeley MHAD data set and apply the Nuitrack software on the depth data.

Thanks for any guidance.

By default, there is no such possibility but you can contact the sales department if there is a need for customization.
