Hi Mohammad and Florian

Thanks a lot for your info. I was away and sick for the past few days so i could not get to work on this till now.

I did the update as you suggested and it looks like the example is working but my eic is not quite running properly.

root does not give me any errors actually but it is also not producing anything in the root files. I am puzzled by this information given to me by root.

I do not understand what does it mean when it says that the geantino has more than 1000 steps.

Also, just another point on the example rutherford, i am still not able to see any tracks on the event display. Is it something to do with initializing tracks in the eventDisplay.C macro?

Regarding the tracks, it does like when i try to set any cuts. (this i am very doubtful on because sometimes it takes it and other times it does not take it)

Another question i have is, does the matter of initializing the box generator, set tracks etc.. in the macro count? (it may be a very stupid question in that it obviously counts, but i would like a general solution like first i define this, then that etc...)

Thanks a lot for all your help
