Errror Accessing RooFit 'custom' PDF saved in root file

asartim · December 11, 2008, 12:05pm

Dear all,
I’m using a PDF created with RooClassFactory (named Acceptance) to perform a Fit.
The code compiles and runs.
The Acceptance.* files are created using the RooClassFactory methods and compiled: the shared libraries used to link the application.

The fit is ok and I save it in a file (using the ->Write() methods).
I save the likelihood and the dataset. Later I can access them in the save file without problems.
But When I try to save the PDF inside the file I fail to read it back. (I need the PDF because I want to reobtain the likelihood scans after the fit is finished).

When I load the file I see:
Warning in TClass::TClass: no dictionary for class Acceptance is available

The pdfs have been saved:
root [1] _file0->ls()

TFile** Sim_data_stri_FitRes.root
TFile* Sim_data_stri_FitRes.root
KEY: RooFitResult L;1 @0+@1+@2-@3
KEY: RooAddPdf pdf_fit_BS2KK;1 Total(B+S) BS -> K+ K- PDF
KEY: RooDataSet pdf_fit_BS2KKData;1 Generated From Total(B+S) BS -> K+ K- PDF
KEY: RooAddPdf pdf_fit_BS2Kpi;1 Total(B+S) BS -> K+ pi- PDF
KEY: RooDataSet pdf_fit_BS2KpiData;1 Generated From Total(B+S) BS -> K+ pi- PDF
KEY: RooAddPdf pdf_fit_BS2piK;1 Total(B+S) BS -> pi+ K- PDF
KEY: RooDataSet pdf_fit_BS2piKData;1 Generated From Total(B+S) BS -> pi+ K- PDF

But When I try to access them I have the bad crash appended below.

How can I add the class dictionary to ROOT?
I am doing:
#include </home/asarti/roofit/b2hh/B2hhFit/Acceptance.h>
and
gSystem->Load(“Acceptance_cxx.so”);
in my macro…
Am I missing something stupid?

The same also applies when using a compiled code. The crash is appended Below the one of the macro.

Thanks,
alessio

Hi,

The class version 0 indicates that you do NOT want to do I/O for this class but the error messages indicates that you are indeed attempting to do so .

UseClassDef(Acceptance,1) // Your description goes here...

Also you need implement either a default constructor or a constructor take one argument of type TRootIOCtor*.

Cheers,
Philippe.

asartim · December 11, 2008, 8:26pm

Also you need implement either a default constructor or a constructor take one >argument of type TRootIOCtor*.

Sorry,
can you please provide me an example or a little bit more detail on what you mean?
An where am I supposed to write/use this default constructor? Inside Acceptance or in my code accessing it?

thank you so much for your kind help
alessio

pcanal · December 11, 2008, 8:32pm

Hi,

You just need to add a proper default constructor for the class Acceptance.

class Acceptance { int fValue; public: Acceptance() : fValue(-1) {}; };

Cheers,
Philippe.

asartim · December 11, 2008, 9:35pm

Great, now the errors are nearly all gone.
ButI’m left with a nasty

followed by the log pasted below.
If I use the compiled version and use gdb I get

Hi,

Maybe you are trying to call ‘Get’ on a TDirectory and/or TFile that has already been deleted?

Philippe.

asartim · December 12, 2008, 3:16pm

No,
It’s not that easy.
Nothing to do with opening/cd of anything.
In my macro I just do:

#include </home/asarti/roofit/b2hh/B2hhFit/Acceptance.h>

void MacroLikeScan() {

TFile f("/home/asarti/roofit/b2hh/B2hhFit/Sim_data_stri_FitRes.root");
int sigplbkg = 0;
f.ls();
cout<<"Started "<<endl;
RooFitResult * result = ((RooFitResult*)gDirectory->Get(“L”));
RooDataSet * pl_data = ((RooDataSet*)gDirectory->Get(“pdf_fit_BS2piKData”));
//Acceptance * accBS2piK = ((Acceptance*)gDirectory->Get(“accBS2piK”));
cout<<"Ended "<<endl;
return;
}

But If I uncomment the Acceptance retrieval the macro crashes and do not reach the end… The ‘Started’ cout is obtained, so the ls of the file is not causing troubles…

I’m really puzzled.
Alessio

pcanal · December 12, 2008, 3:57pm

Can you try:RooFitResult * result = ((RooFitResult*)f.Get("L")); RooDataSet * pl_data = ((RooDataSet*)f.Get("pdf_fit_BS2piKData")); Acceptance * accBS2piK = ((Acceptance*)f.Get("accBS2piK"));

Philippe.

PS. Actually a safer syntax issue:RooFitResult * result; f.GetObject("L",result); RooDataSet * pl_data; f.GetObject("pdf_fit_BS2piKData",pl_data); Acceptance * accBS2piK; f.GetObject("accBS2piK", accBS2piK);where the pointer are initialized to zero if the requested name point to an object of the wrong type.

asartim · December 12, 2008, 4:07pm

I have tried both. But the crash remain.

The compiled version under gdb tells me:

Program received signal SIGSEGV, Segmentation fault.

Hi,

The macro you showed does not contain the necessary:

gSystem->Load(“Acceptance_cxx.so”);

Is it done outside of your macro?

Hi,

It is difficult to write single RooFit objects to a TFile like you do because they contain pointers to other objects. There exists a special container class RooWorkspace that you can use to persist (clusters of) RooFit objects safely

A complete example on how to do this is given here:

$ROOTSYS/tutorials/roofit/rf502_wspacewrite.C
