Hi experts,
I am trying to build a TTree with custom object branches using RDataFrame.
Unfortunately, I get a Segmentation Violation error. After some tests I figured out that it might be related to Snapshot not properly recognizing my user-defined type. I tried also to explicitly specify the types in the template of the snapshot but nothing.
I paste here the relevant parts of the code:
#include <ROOT/RDataFrame.hxx>
#include <TInterpreter.h>
typedef struct {
double sqFall, sqFallErr;
double sqRise, sqRiseErr;
double sqWdt = sqFall - sqRise;
double sqWdtErr = TMath::Sqrt(sqFall*sqFall + sqRise*sqRise);
} Square_Signal;
typedef struct {
Square_Signal start;
Square_Signal stop;
double dtFall = stop.sqFall - start.sqFall;
double dtFallErr = TMath::Sqrt(stop.sqFallErr*stop.sqFallErr + start.sqFallErr*start.sqFallErr);
double dtRise = stop.sqRise - start.sqRise;
double dtRiseErr = TMath::Sqrt(stop.sqRiseErr*stop.sqRiseErr + start.sqRiseErr*start.sqRiseErr);
} Decay_Event;
Decay_Event GetSameChSquare( RVec<double> vFall, RVec<double> vFallErr, RVec<double> vRise, RVec<double> vRiseErr ){
Square_Signal start = { vFall[0], vFallErr[0], vRise[0], vRiseErr[0] };
Square_Signal stop = { vFall[1], vFallErr[1], vRise[1], vRiseErr[1] };
Decay_Event decay = { start, stop };
return decay;
}
int main(int argc, char** argv)
{
//declare my struct data types
gInterpreter->Declare("typedef struct {double sqFall, sqFallErr; double sqRise, sqRiseErr; double sqWdt = sqFall - sqRise; double sqWdtErr = TMath::Sqrt(sqFall*sqFall + sqRise*sqRise);} Square_Signal;");
gInterpreter->Declare("typedef struct {Square_Signal start; Square_Signal stop; double dtFall = stop.sqFall - start.sqFall; double dtFallErr = TMath::Sqrt(stop.sqFallErr*stop.sqFallErr + start.sqFallErr*start.sqFallErr); double dtRise = stop.sqRise - start.sqRise; double dtRiseErr = TMath::Sqrt(stop.sqRiseErr*stop.sqRiseErr + start.sqRiseErr*start.sqRiseErr); } Decay_Event;");
//setting I\O file names
...
//
//open file(s)
TChain myChain("amulet");
for(auto measN : measNs)
myChain.Add( (inDir+"run"+runN+"meas"+measN+"_amulet.root").c_str() );
ROOT::EnableImplicitMT(); //the problem persists also with MT disabled
//create df
ROOT::RDataFrame d(myChain);
//define filters and print report
auto upDecays = d.Filter(ch0NupNdwn, "Ch0 Nup == Ndwn").Filter(UpDecayCut, "UpDecay (ch0Nup==2)");
upDecays.Report()->Print();
//up to this point everything seems to work
//evaluate lifetimes from digital signals defining new columns in the dataframe
auto dtUpDec = upDecays.Define("decayUP" , GetSameChSquare, {"ch0timedwns","ch0timedwnsErr","ch0timeups","ch0timeupsErr" } ).Snapshot<short int, long long unsigned, Decay_Event>("DeltaT UpDecays", OutFileName.c_str(), {"measN","idx","decayUP"} ); //segmentation violation
return 0;
}
I paste here the output of the code:
Ch0 Nup == Ndwn: pass=61 all=62 -- eff=98.39 % cumulative eff=98.39 %
UpDecay (ch0Nup==2): pass=28 all=61 -- eff=45.90 % cumulative eff=45.16 %

I would appreciate any help,
