2.5M events for 4.4GeV, 5.5GeV, 6.6GeV, 11.0GeV at http://hallaweb.jlab.org/12GeV/SoLID/download/test_generator.tgz

Following is shown a tool to convert and play with the output of the event generator https://jlabsvn.jlab.org/svnroot/solid/evgen/root_to_lund/

ROOT TO LUND CONVERSION

I modified my root to lund conversion so that one can filter the data 
based on the angle of scattering of the electron.
I have also put the option to use a "lund format" file as input for 
filtering based on the angle (you have these files right now).
There is also an option to have in the output a geantino or a charged geantino, rather than the electron.


          

If you running without flags you get this message (how to use it):

 root2lund : This Program translate the output from eicRate in LUND format and Filter the scattered electron angles
 Usage: root2lund -o outputfile -i inputfile [-th_min theta_min] [-th_max theta_max] [-ph_min phi_min] [-ph_max phi_max] [-l 1-0] [-g 2-1-0]
     -o outputfile     : output file name (example pluto.lund)  
     -i inputfile      : input file name (example pluto.root)  
     -h help, print this message 
   [optional] 
     -th_min theta_min : specify theta minimum for scattered electron 
     -th_max theta_max : specify theta maximum for scattered electron 
     -ph_min phi_min   : specify phi minimum for scattered electron 
     -ph_max phi_max   : specify phi maximum for scattered electron 
     -l 1-0            : specify format input file ( lund-> 1 (just angle filtering); root->0 (default) )
     -g 2-1-0          : specify if particle in output is a geantino ( geantino-> 1 ; charged geantino-> 2 ; normal->0 (default) )
