-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. +Overview: This script ({{:itk:channelextraction.py|}}) 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 the channels.

 +  * Download the package using the command

 +wget https://atlaswww.hep.anl.gov/asc/wikidoc/lib/exe/fetch.php?media=itk:channelextraction.py -O ChannelExtraction.py 
 +</code> 
 +  * Once you have the package, make sure that you have already installed ROOT or can open the ROOT file from your test. 
 +  * Open the script ''vim (or emacs/whatever text editor you use) ChannelExtraction.py''. 
 +  * Input your ROOT file that contains the histogram from the test, the name of the histogram, and the maximum number of hits possible in all of the channels. 
 +  * Save script. 
 +  * Run script using ''python ChannelExtraction.py''  
 +  * The information will be printed to the command line.
