Hi ROOT experts,
I am trying to modify an analysis macro to be able to use the Option_t parameter in “Process”.
Here’s some relevant code from runAnalysis.C:
// Headers
void runAnalysis (int job = 0) {
TChain chain("dy");
if(job==0) chain.Add("data_A.root");
if(job==0) chain.Add("data_B.root");
if(job==1) chain.Add("data_C.root");
if(job==1) chain.Add("data_D.root");
// Here goes some code that converts int "job" to a string "job_string"
chain.Process("myTSelector.C++", job_string);
}
But that doesn’t work as it seems the option parameter must be a constant. So while I’d be able to get it to work by including/modifying the following lines:
const char fakejob[] = "1"; // included at the top
...
chain.Process("myTSelector.C++", fakejob); // modified at the bottom
that is no help in being able to pass the information (int job) used when calling runAnalysis.
Is there a way around this or is this a limitation of Option_t?
