Introduction

• Need to develop an Analysis Framework for the
  data coming from 84 channel/cell tower
• Several options for analyzing data PAW, JAS,
  ROOT, Origin, Excel
• But we need to do more than just maniplate and
  analyze one histogram at a time we need to
  analyze data from each of the 84 channels the
  same way so that they can be compared.
• Need to automate analysis process with
  scripts/macros
• Want to create a user interface
• to display the 84 channels in a way that they can
  be compare
• to set parameters with buttons and other controls

3
Tasks we need to do repeatedly include

• Remove pedestal
• Remove crosstalk
• Fit multiple gaussians, poissons and landau
  curves to histogram (all 84 channels)
• Enter data conditionally into histograms (for
  example only add event data from Channel X if
  events from Channels Y and Z are in MIP range)
• View channel data by layer or column
• View Scatter plots
• Want to see if we can track particles

Which is better Kurts VB software, PAW, JAS,
ROOT?
5
Kurts VB Software

• Advantages
• Kurts familiar with it
• Easy to create and modify User Interface easy
• Displays data in a way that you can compare
  channels on screen at same time
• Disadavantages
• No good fitting algorithms
• Dont think anyone else would want to use VB
• Important stuff, math functions, not debugged
• Doesnt have large experience base of all other
  systems

6
PAW

• Advantages
• accurate fitting
• Disadvantages
• older
• Fortran, never wanted to learn Fortran
• display not as impressive
• no way to create user interface
• commands somewhat cryptic

7
JAS

• Advantages
• Java Ive always wanted to learn JAVA
• NICADD people have JAVA background
• Disadvantages
• havent figured out how to do create a user
  interface
• tutorial okay but not enough examples

8
ROOT

• Advantages
• C, Ive always wanted to learn C
• was able to figure stuff out faster than with JAS
• interpreted dont have to wait for compiling
• good macro examples / tutorial
• Disadvantages ???

Summary

• Currently, I prefer ROOT because I learned how to
  do more in less time that JAS
• Im sure other people have some other opinions
  and Id like to hear them
• Next step test to see if I can create simple
  user interface with Root
• Also, test to see if LabView data collection
  software to write out data in Ntuples instead of
  text.( If not can just write simple utilty that
  converts from text to Ntuples.)
