PROOF with Event structures

ROOT
1

Hi,

I would like to use PROOF to run on my own event structure, which is very similar to the Event.cxx example that comes with root. The only example I found uses MakeSelector to produce a selector to run in PROOF. MakeSelector does not yet work wioth more complex structures such as TCLonesArrays and TRefArrays last I heard.

Is there a way to use PROOF on an event structure without using MakeSelector. An example or doc would be very helpful.

Thanks,

Alex

I think I just have to essentially create the appropriate selector inheriting fromTSelector by hand. I will use the makeselector stuff but gut it out, keeping the required methods.

Hi,

One approach is our TAM package:

higweb.lns.mit.edu/tam/

On a side note, what is the problem with MakeSelector and your tree?

Thanks,

Maarten

I’ll have a look at that.

In the past MakeSelector did not work with TClonesArrays and/or TRefArrays (I can’t recall which one or whether it was both that were not yet supported).

Thanks,

Alex
