+
=== Acquiring the Virtual Machine ===
−
* Talk (20 mins): Intro to JANA/DANA (factories & plugins)
+
−
** JANA is a framework: multithreaded, factory-based (describe concept of factories, tags (e.g. BCAL)), event-processors control the work flow
+
−
** The primary executable (hd_root) does virtually nothing by itself, the processor in your plugin tells it what to do
+
−
** JANA automatically loops over the events in your input files, executing the primary factory & plugin methods as needed: init(), brun(), evnt(), erun(), fini()
+
−
** hd_dump: Prints data to screen
+
−
** DMCThrown and DKinematicData
+
−
* Exercise (10 mins):
+
−
** Print the kinematics of the thrown particles to screen via hd_dump and inside of plugin (all three kinds)
+
  
−
* Talk (15 mins): Reconstruction and Data Classes
+
* The virtual machine can be acquired via either the UConn SRM (if you have open science grid (OSG) access) or via JLab.
−
** Track/Shower reconstruction, Hypotheses, REST format, danarest plugin
+
** 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). 
−
** Basic Analysis Classes: DKinematicData, DChargedTrackHypothesis, DChargedTrack, DNeutralShower, DMCThrown, DBeamPhoton
+
  
−
* Exercise (20 mins):  
+
* '''UConn SRM''' ([https://halldweb.jlab.org/wiki/index.php/Using_the_Grid Using the Grid]):  
−
** Use danarest plugin to do track reconstruction.
+
** Via Web Browser: Goto https://grinch.phys.uconn.edu:2880/Gluex/test/ and right-click and download the GlueX_Analysis_Workshop.ova file.
−
** Print basic analysis objects (DChargedTrackHypothesis, etc.) to screen via hd_dump and inside of plugin
+
** Via srmcp:
 +
*** "srmcp srm://grinch.phys.uconn.edu:8443/Gluex/test/GlueX_Analysis_Workshop.ova 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 https://halldweb.jlab.org/dist/ 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 username@ftp.jlab.org" (where "username" is your jlab username)
 +
*** "cd /group/halld/www/halldweb/html/dist/"

Latest revision as of 17:10, 24 February 2017

Purpose

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).

  • A detailed wiki providing supplementary materials and solutions to the exercises regarding the workshop is located here.

Software and Data from the Workshop

Acquiring the Virtual Machine

  • 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 https://grinch.phys.uconn.edu:2880/Gluex/test/ and right-click and download the GlueX_Analysis_Workshop.ova file.
    • Via srmcp:
      • "srmcp srm://grinch.phys.uconn.edu:8443/Gluex/test/GlueX_Analysis_Workshop.ova 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 https://halldweb.jlab.org/dist/ 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 username@ftp.jlab.org" (where "username" is your jlab username)
      • "cd /group/halld/www/halldweb/html/dist/"
      • "get GlueX_Analysis_Workshop.ova"

Setting up the Virtual Machine

On the virtual machine, before doing the exercises:

  • cd $SESSIONS
  • svn update
  • cd $ANALYSIS_SCRIPTS
  • svn update -r11298

This will give you the updated exercise software and analysis plugin generation scripts.

Software (32-bit builds)

Locations on Virtual Machine

  • Exercises: $SESSIONS
  • Data: $GLUEX_DATA
  • Analysis plugin generation scripts: $ANALYSIS_SCRIPTS
