The purpose of this tutorial/workshop session will be to give an introduction to using the Hall-D analysis tools. It is open to anyone either inside or outside the GlueX collaboration who has an interest in doing physics inside Hall-D. The tutorial will cover the basics of:

  • Physics Analysis Framework
  • Using Boosted Decision Trees
  • Amplitude Analysis using AmpTools

The tutorial will consist of a series of talks with exercises, along with room for questions/discussion.

Location and Time

The tutorial will take place:

DATE: July. 10-11, 2013

TIME: 8:30am to 5:30pm EDT (i.e. JLab time).

LOCATION: CEBAF Center L102 - L104

Registration & Requirements

  • Registration Page
  • Participants
  • All attendees are required to bring their own laptop to the workshop.
    • It must have enough memory (4+ GB RAM preferred) and free hard disk space (~15+ GB) to run a virtual machine, which will be distributed at the workshop.
    • It must have VirtualBox installed (v4.2.14 or later): Download VirtualBox
    • If you are attending remotely, instructions for obtaining the virtual machine image are below.

Remote Participation

To connect from the outside by phone please do the following

1.) ESNET: 8542553

2.) Polycom RealPrescence App for iOS and Android. Call

3.) Telephone:

Dial +1-866-740-1260 : US and Canada

Dial +1-303-248-0285 : International

Then use participant code: 3421244# (the # is needed when using the phone) or then type access code 3421244 into "join a meeting" (you need java plugin)

4.) Desktop Sharing

You can view the computer desktop in the meeting room at JLab via the web.

  1. Go to
  2. In the "join a meeting" box enter the Hall D code: 3421244
  3. Fill in the participant registration form.

5.) As of January 1, 2013 EVO became SeeVogh and Jefferson Lab has a contract to use it.

   To connect via SeeVogh, vist their website at Your old EVO credentials are supposed to work. There will be a room booked for the meeting.
   To phone into an EVO meeting, from the U.S. call (626) 395-2112 and then enter the EVO meeting code. Instructions for the Phone Bridge to EVO.
   Skype Bridge to EVO 

6.) Please visit the Communications page for some options.

Acquiring the Virtual Machine Remotely

  • The virtual machine can be acquired via either the UConn SRM (if you have open science grid (OSG) access) or via JLab.
    • The file is very large (over 5 GB), so the download will likely take a long time if you have a slow internet connection (and will likely be fastest if you copy it while on-site at a university).
  • UConn SRM (Using the Grid):
    • Via Web Browser: Goto and right-click and download the GlueX_Analysis_Workshop.ova file.
    • Via srmcp:
      • "srmcp srm:// file:////localdir/GlueX_Analysis_Workshop.ova", where "/localdir" is the full path to the directory you want to download it to.
  • JLab:
    • Via Web Browser: Goto and right-click and download the GlueX_Analysis_Workshop.ova file.
    • Via sftp:
      • On your own machine, "cd" to the folder you want to download it to.
      • "sftp" (where "username" is your jlab username)
      • "cd /group/halld/www/halldweb1/html/dist/"
      • "get GlueX_Analysis_Workshop.ova"
