I’ve included the example code that I have been using.
The Process method I’m thinking of is the TProofChain::Process method that takes a pointer to a TSelector. This method throws and exception that its not implemented, sorry about that.
Currently I’m trying to get the cms TFWLiteSelector example to work as well. No luck yet.
I’m running under cms_1_6_0_pre9. I’m just looking for a solid example that works such that I can test the proof cluster.
Example Macro ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
{
gSystem->Load(“libFWCoreFWLite”);
AutoLibraryLoader::enable();
gSystem->Load(“libPhysicsToolsParallelAnalysis”);
TString dcache = TString(“root://dcache-00.rcac.purdue.edu/pnfs/rcac.purdue.edu/data”);
char *files[] = {
"/store/RelVal/2007/8/2/RelVal-RelVal160pre7SingleMuPlusPt100-1186055203/0000/ECF4535E-0241-DC11-B787-0030485610BC.root",
NULL
};
TChain chain(“Events”);
int index = 0;
while(files[index]!=NULL){
TString filename = TString(files[index]);
filename.Prepend(dcache);
std::cout<<filename<<endl;
chain.Add(filename);//
index++;
}
cout<<“There are “<<chain.GetEntries()<<” events”<<endl;
chain.MakeSelector(“TestSelector”);
}
