Overview

  1. EVIO data files are converted to LCIO Data Format and within the same process, the HPS Java reconstruction is run to produce physics object collections.
    1. Event skimming using filters performed in separate EVIO to LCIO jobs.
  2. The LCIO is converted to ROOT DST Data Format so that the events can be easily analyzed in ROOT.
  3. DQM files containing plots in ROOT or AIDA format may also be produced from the reconstruction output.

EvioToLcioJeremy McCormickorg.hps.evioThe main program that converts EVIO to LCIO, performing an LCSim job in the same session. The processed events are then (optionally) written to disk using an LCIOWriter.
LCSimEngRunEventBuilderJeremy McCormickorg.hps.evioThis is the LCSimEventBuilder implementation for the Engineering Run and the Commissioning Run.
EcalEvioReaderSho Uemuraorg.hps.evioConverts various modes of EVIO TDC information into LCSim hit collections.
