  The SST-1M telescope is one of the prototypes under construction proposed to
be part of the future Cherenkov Telescope Array. It uses a standard
Davis-Cotton design for the optics and telescope structure, with a dish
diameter of 4 meters and a large field-of-view of 9 degrees.
  The innovative camera design is composed of a photo-detection plane with 1296
pixels including entrance window, light concentrators, Silicon Photomultipliers
(SiPMs), and pre-amplifier stages together with a fully digital readout and
trigger electronics, DigiCam.
  In this contribution we give a general description of the analysis chain
designed for the SST-1M prototype. In particular we focus on the calibration
strategy used to convert the SiPM signals registered by DigiCam to the
quantities needed for Cherenkov image analysis. The calibration is based on an
online feedback system to stabilize the gain of the SiPMs, as well as dedicated
events (dark count, pedestal, and light flasher events) to be taken during the
normal operation of the prototype.
