Hello! A beginners question: How do I store and process arrays (16x16 Bytes) as event-data? I would like to store one array per event in an NTuple or such. I want to do some manipulation on the data as computing means, subtracting pedestals and eliminating bad events. Afterwards I need to do some histograms and statistics. Can I use the NTuple-class for my purpose? I have seen that it is possible to allocate arbitrary variables and store the data via pointer. But how do I get the data back out? Or do I have to write my own TTree subclass and which methods does it have to have? Hope for some advice Robert
