This is an example LCIO program to demonstrate the structure for an input file needed for the first processor of the simulation package TPCGEMSimulation. This program creates cosmic muons. Typing make will create the executable CreateMuonsLCIO. Usage CreateMuonsLCIO "Number of events to be created" "tpc outer radius" "tpc length" "muonenergy.dat" The file muonenergy.dat can be found in TPCGEMSimulation/inputs. Change the code for a specific energy or different angular distribution etc.
