To run the simulation + reconstruction macro

cd e1039-analysis/SimChainDev/
root -l eve_disp.C

To run real data reconstruction:

cd e1039-analysis/CODAChainDev/

ln -s /seaquest/production/runs/run_028692 .
root -l eve_disp.C

A GUI like this should pop up: Click Next Event to run and show the next event

Then 3 tabs should show up in the main window.

• Viewer 1: the main tab
• Station View: station-by-station view
• Hodo View: show only hodo hits in X-Z and Y-Z view

• The Event ID and Trigger NumberEntry specifies the EventID or Trigger type you are interested. -1 means not specified. Please use only one selection (either Event ID or Trigger) for now
  • Trigger bit to trigger type mapping: here
• These three buttons on the left panel, Top View Side View and 3D View, only control the main view (Viewer 1)
• The graphics runs slow using remote connection, give it some time refresh. You may use the terminal window to check the status
  • For me even under the same network, the graphics seem slower in Mac OS than Linux

• Left button drag: rotate
• Middle button drag: pan
• Middle button scroll: zoom
