This is the basic recipe for reconstructing HPS data:

1. EVIO data files are read in and converted to LCIO events using the EvioToLcio command line utility events.
2. The HPS Java reconstruction is run to produce add physics object collections to the events.
3. The events are written to an LCIO file containing results of the recon.
4. The recon LCIO is file can be converted to ROOT DST Data Format so that the events can be easily analyzed in ROOT.

Oftentimes, the physics reconstruction is steps 1-3 are performed in the same job (process) as the conversion from raw data to LCIO for efficiency , typically using the EvioToLcio command line utility.
