Jet Flavour Tagging Howto

Line: 129 to 129
 For b-tagging, we've compared the plot produced by MakePurityVsEfficiencyRootPlotGla.C and graphs drawn with the data tabulated in PurityEfficiencyOutput.txt, for 1, 2, 3 (corresponding to distinct neural networks) or any number of vertices (which we don't know yet how to interpret):

Here's the script used to extract the numbers from PurityEfficiencyOutput.txt.

We had to run processors 1-7 on these files to identify jets and calculate the discriminating parameters. For this, we used slightly modified version of the scripts, which can be found here. The resulting outputs, containing approximately 25k events, are stored in /afs/phas.gla.ac.uk/data/ilc/datasets01/1.4tev/ZVRES_out/ as well.
