Extracting channels from ROOT files
Overview: The TestAnalysis.py script allows the user of the HSIO to print off specific problematic channels after running a test. The user inputs the root file from the test, the specific histogram they would like to analyze, and must put the maximum number of hits possible in a given channel.
Instructions:
Script:
#This script allows the user to see the specific ouput for specific pixels on different electronic tests
<code>
from ROOT import *
#The user must input the root file, histogram, and the maximum number for bin content
fileName = “”
histogramName = “”
maxValBin = 50
#Do not modify the rest of the code, it should work given what the user has place above.
test = TFile.Open(fileName)
h = test.Get(histogramName)
h.Draw(“colz”)
for i in range(1, h.GetNbinsX()):
for j in range(1, h.GetNbinsY()):
binContent = h.GetBinContent(i, j)
if binContent < maxValBin:
print “*”
print “Pixel column (x): ”, i
print “Pixel row (y): ”, j
print “Number of hits: ”, binContent
print “*”
</code>
