Extracting channels from ROOT files
Overview: This script allows the user to print a list of 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 input the maximum number of hits possible in a given channel.
Instructions: testanalysis.py Script: testanalysis.py
- TestAnalysis.py
#This script allows the user to see the specific ouput for specific pixels on different electronic tests from ROOT import * #The user must input the root file, histogram, and the maximum number for bin content fileName = "path/to/file.root" histogramName = "name of histogram" 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 "*****************************"
