-Another approach is to use [[http://jwork.org/dmelt/ | DataMelt]] that gives more flexibility and more libraries for analysis. 
-In this example, we will run a Python script that downloads data from URL into the computer memory  and runs it in a batch mode. First, you will need an analysis code from HepSim. Look at ttbar sample from Madgraph: [[http://atlaswww.hep.anl.gov/hepsim/info.php?item=15 | ttbar_mg5]].  Find the URL location of the analysis script ("ttbar_mg5.py") located at the bottom of this page. Then copy the URL link of the file *.py using the right mouse button ("Copy URL Location"). Let us make a calculation of differential ttbar cross section:
