ROOT Analyzer/Running
From HallCWiki
The current Hall C C++ analyzer code does not do anything useful except for reading in Hall C style CTP parameter files.
To run the analyzer, type
./hcana
Once it starts up, type
gHcParms->Load("hctest.input")
To dump the parameters read
gHcParms->PrintFull()
Some examples of accessing individual variables
analyzer [3] Double_t ProtonMass = *(Double_t *)gHcParms->Find("proton")->GetValuePointer(); analyzer [4] ProtonMass (Double_t)9.38272000000000048e+02
analyzer [5] Int_t *integerarray = (Int_t *)gHcParms->Find("integerarray")->GetValuePointer(); analyzer [6] integerarray[3] (Int_t)4
