HowTo look at the objects in the event(banks, collections etc.)

You can use evd to look at the objects in the event:

//to list banks:
list()
//to list objects (collections, storable banks ...):
list("edm")
//to dump bank:
dump("CMXD")
//to dump object by its id number
dump_object(218)
//to dump object by its name
dump_object("CdfTrackColl")
// i.e. format of dump_object routine is as follows:
// int dump_object(char* name, char* format = "0")
// int dump_object(int id)

If you want to put output to the file, do:
list("edm") ; > list_edm.output 
to see list_edm.output from the ROOT prompt you should type:

.!less list_edm.output
