Writing a configured TMVA::Reader to a TFile

When using PROOF, I’m used to serializing all my ROOT objects so they can be transmitted to various PROOF slaves.

I’ve just started using TMVA, and it looks like TMVA::Reader, though you can write it out to a file, doesn’t save everything it needs to run.

Is this correct? Generally, does one have to ship the weight file, and create it on every slave?

Many thanks!

Hi Gordon,

The information the Reader needs to run is in the XML file. So I guess you need to have every slave have a copy of the files.
I am not sur instead if the streaming of the full method classes will work.
