Software

DAQ software is in /u1/software/daq; run all commands from this directory.

Run "source setup_env.csh" before running any commands.

Start the GUI: "./bin/trackerGui"

Run a calibration script (trackerGui must be running): "python scripts/calibrate.py"

Scripting

Python scripts use the commands defined in python/pythonDaq.cpp - if you make changes there, you can run "make" in the "python" directory to rebuild the Python module.
