Analysis commands

Converting files to ROOT

~/src/CLAS/coatjava-1.0/bin/run-groovy Evio2Text.groovy eg12_rec.0.evio > Sim.dat

edit Sim.dat and remove the first few lines until you have only numbers

minerve2:~/src/CLAS/GEMC/experiments/eg12/lh2> root -l root [0] .L Asci2Root.C root [1] Asci2Root("Sim.dat");

Using ROOT to analyze a file

minerve2:~/src/CLAS/GEMC/experiments/eg12/lh2> root -l Sim.root
