Running Reconstruction

These instructions assume "hps-java.jar" is the hps-java jar file you downloaded using the instructions on Basic Use of hps-java, or compiled yourself.

The input data for this step is readout data; use either real 2012 test run data (EVIO format) or generate from simulation using the instructions in Running Readout Simulation.

Reconstructing readout data (either real data or output of readout simulation)

Use TestRunOfflineRecon.lcsim for both test run data; substitute HPS2014OfflineRecon.lcsim for simulated 2014 data.

One-step process (EVIO to recon'ed LCIO)

java -cp hps-java.jar org.lcsim.hps.evio.TestRunEvioToLcio -r -x /org/lcsim/hps/steering/recon/TestRunOfflineRecon.lcsim -d HPS-TestRun-v3 prod/hps_001351.evio.0 -DoutputFile=recon.slcio

Note: the "-d HPS-TestRun-v3" specifies the detector to be used in the reconstruction and is required. "HPS-TestRun-v3" is the latest as of this note, but make sure you ask the production manager about what detector to use for your purpose.

Two-step process (EVIO to raw LCIO to recon'ed LCIO)

java -cp hps-java.jar org.lcsim.hps.evio.TestRunEvioToLcio -d HPS-TestRun-v3 prod/hps_001351.evio.0 -l raw.slcio
java -jar hps-java.jar -r /org/lcsim/hps/steering/recon/TestRunOfflineRecon.lcsim -i raw.slcio -DoutputFile=recon

Reconstructing LCIO data from readout simulation (raw LCIO to recon'ed LCIO)

This is just the second half of the two-step process.

java -jar hps-java.jar -r /org/lcsim/hps/steering/recon/TestRunOfflineRecon.lcsim -i raw.slcio -DoutputFile=recon

Reconstructing SLIC output directly

java -jar hps-java.jar -r /org/lcsim/hps/steering/readout/HPSTrackingDefaults.lcsim -i ap2.2gev075mev_001_SLIC.slcio -DoutputFile=ap_recon.slcio
