BaBar Software Tutorials

New tutorials are in development. We'll include sessions on Composition Tools, Objectivity, and event generators, starting in October.

(See schedule below.)

Announcing...

A new series of bi-weekly BaBar Software Tutorials is being scheduled. The purpose of these tutorials is to make available regular training sessions on aspects of BaBar software in common use.

Sessions will be held at SLAC on alternate Mondays at 3:00 PM in the SCS training room on the first floor of the Computer Group Building. Sessions will last about an hour.

Webcasting...

These tutorials will be webcast live during the sessions: click the "Next Webcast" link on the SLAC streaming media page at the scheduled start time of the next tutorial. (Important: if you bring this link up in your video player and it says "Please stand by", the webcast hasn't started yet. When it does start, you must click the webcast link again to get the actual broadcast.)

These sessions are also recorded on video and made available on the web a few days after the initial broadcast. They can be found on the BaBar Software Tutorials Media Files page.

Future tutorials may include such topics as:

• Beta/Kanga intro
• Root
• What you can do with beta candidates
• Vertexing, Composition Tools
• PID Tools
• Charged/Neutral Tracking

Hints for instructors:

For a successful web presentation, remember:

• Wear a dark, solid-colored shirt. No stripes! They may produce weird moire patterns in the video.
• Use large fonts in the material to be displayed. Normal size fonts are often not readable in the webcast using current cameras and digitizing software.
• See Tips for web video presentations for more information.

Regularly-scheduled Tutorials

Live webcasts may be viewed from the SLAC streaming media page.

Past Tutorials

Past tutorials may be viewed from the BaBar Software Tutorials Media Files page.

Monday 31 July 2000	Using Nano-micro Quantities Chris Roat	This tutorial demonstrates: Loading the nano(tag) database, which contains the global event quantities and the tag bits for an event. Inspecting the tag database quantities for an event and accepting it if it passes your general criterion. Loading the micro database for accepted events, which contains more detailed information about the event. Performing your analysis, which can include vertexing, composition, and other tools.
Monday July 24, 2000	Using the BaBar Framework Dan Azzopardi	This tutorial discusses the framework and how it is used within BaBar.
Monday July 17, 2000	The Pico Analysis Framework (PAF) Marcel Kunze	PAF is a ROOT-based framework for physics analyses based on ROOT files. It is a light-weight product that allows to reuse Kanga data files together with the original Beta analysis libraries. It emphasizes the interactive regime, hence it is very fast: on a modern PC, it should be possible to do data-mining in a set of up to 100 million events in less than 1 hour, i.e., it is possible to start an analysis from the complete dataset in order to learn the correct settings for a perfect skim. This tutorial demonstrates the installation, use and advantages of the PAF system. It builds upon the earlier SLAC software tutorials and is written in the same style for your convenience. It shows how you can run a simple Beta module within PAF and how you can tune the speed by a factor of 20. Note: be aware that PAF is not BaBar-supported. PAF has been mainly developed by the german collaborators and is currently supported by Bochum University. While it is an interesting tool, it is not yet verified for official BaBar use.
Monday June 19, 2000	ROOT Tutorial Urs Langenegger	This tutorial will demonstrate the use of Root for interactive analysis of a Root file and for peeking at Kanga files: Fundamentals (environment, GUIs, definitions) Doing simple interactive analysis with trees and histograms Build your own trees (two examples - a trivial 'ntuple and a more advanced tree) Put this tree into a Beta Module
Monday May 15, 2000	Beta/Kanga Introduction Leon Rochester and Ray Cowan	This tutorial demonstrates how to run a simple Beta job in two modes: Reading data from the Objectivity event store and writing histograms to an Hbook file; and Reading data from a Kanga file and writing histograms to a ROOT ntuple. These are followed by a third example illustrating how to run a somewhat more complex job in batch. Note: This tutorial is most likely to be helpful to you if you have not run Beta in recent months.
Monday May 1, 2000	WIRED Event Display Joe Perl	This will be a hands-on tutorial covering the installation and use of BaBar's new WIRED Event Display. We will first show how to install Java on your desktop system and will then show how to install and use the WIRED Event Display client application. NT machines will be provided for users to practice the installation, but users are also encouraged to bring their own laptops (Linux, NT, W9x or Macintosh) so that they can go away from the tutorial with WIRED installed on these machines.
