Session 8

8 Dec 2008

Question 1: You are planning to start analysis, where would you go to look for information

• starts http://cms.cern.ch/iCMS/
• goes to physics http://cms.cern.ch/iCMS/jsp/page.jsp?mode=cms&action=url&urlkey=CMS_PHYSICS
• goes to workbook https://twiki.cern.ch/twiki/bin/view/CMS/WorkBook
  • says that would look for a working group
  • thinks of knowing the basics
  • sees how to make an analysis
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookMakeAnalysis
  • asks if needs to create an own module
  • does not understand "bare root" "fwlite mode" but says would click and try to understand
  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookMakeAnalysis#BareRoot
  • thinks this is not what she wants
  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookMakeAnalysis#FwLite
  • says this is the next stage but she really wants to write a module
  • goes to the top and jumps to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookMakeAnalysis#SetEnv
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookSetComputerNode
  • says would read through this and try to run an example
  • reads toc

Question 2: In your analysis, you would have electrons. What is the electron data format, where would you look for information?

• reads the wb leftbar
• sees data format and tiers - is not sure if this is the place but would click
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookDataFormats
  • sees toc
  • asks whether she would look for reco or aod
  • jumps to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookDataFormats#RecO
  • is asked if she finds what the electron data contains
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookDataFormats (reco data format table)
  • srcolls down the table - takes time to find electrons
  • finds the egamma objects and clicks on the collection name
• comes to http://cms-service-sdtweb.web.cern.ch/cms-service-sdtweb/doxygen/CMSSW_2_1_8/doc/html/d8/d18/classreco_1_1Electron.html
  • thinks the time this took was not too bad

Question 3: You would like to see a useful example code to access electron collection

• reads the wb leftbar on the current page
• sees electron analysis
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookElectronAnalysis

Question 4: You would like to know if other poeple are doing a similar analysis. Where would you go?

• scrolls down on https://twiki.cern.ch/twiki/bin/view/CMS/WorkBookElectronAnalysis
• asks if it is fine as she already has some background
• thinks of going to the Higgs page (reads the left bar) and thinks of being in a wrong place
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WebHome from the trailer
• goes to http://cms.cern.ch/iCMS/jsp/page.jsp?mode=cms&action=url&urlkey=CMS_PHYSICS
  • finds physics groups
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/EgammaPOG
  • finds activities and tasks
  • looks if there is someone is working on electrons
  • decides to take the case of Higgs two gamma
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/WebHome from the trailer
• goes to http://cms.cern.ch/iCMS/jsp/page.jsp?mode=cms&action=url&urlkey=CMS_PHYSICS
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/HiggsWG
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/Higgs2G
  • says that know something about the group but does not know who is doing what
• back to https://twiki.cern.ch/twiki/bin/view/CMS/HiggsWG
• back to https://twiki.cern.ch/twiki/bin/view/CMS/Higgs2G
  • knows when they meet
  • imagines that she wants to know which people are working on this channel
  • reads T2 but is not what she wants to know
  • says that from this page she would know the groups convener and the forum * back to https://twiki.cern.ch/twiki/bin/view/CMS/HiggsWG
  • says that before contacting the convener would look in the cvs directory for the code
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/HiggsWGContacts
  • wants to find a name of someone working on h gamgam (not on this page)
• back to https://twiki.cern.ch/twiki/bin/view/CMS/HiggsWG
• goes to https://twiki.cern.ch/twiki/bin/view/CMS/HiggsWGSoftware
  • finds a link to rep.
• goes to http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/CMSSW/HiggsAnalysis/
• goes to http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/CMSSW/HiggsAnalysis/HiggsTo2photons/ * thinks of going to indico page of the meetings
