| [ROOT] histogram display in peak search Kazuyoshi Furutaka 08:27:50 |
| | Dear rooters,
Could someone teach me
1. why the attached script (named 'peakSearchTest.C'),
which try to find candidate of peaks from TH1F "hpx"
in "hsimple.root" using TSpectrum::Search(), DISPLAYS
the histogram when run as an unnamed script
(.x peakSearchTest.C), whereas it does not when run
as a named one (by invoking peakSearchTest() after
loading the script (or `.x peakSearchTest.C`), of
course after uncommenting the function name in the
script and commenting out the first curly brace.)?
In the latter, only an empty canvas is displayed...
(though a candidate is successfully found)
2. whether it is possible to seach peaks using TSpectrum::Search()
without displaying any canvas/histogram (or control
its display) in interactive root sessions (i.e. w/o
-b option) or not?
Even though the histogram is not explicitly drawn,
the attached script (when run as unnamed one) displays
it.
Thanks in advance.
Yours,
Kazuyoshi

| How to use BC's .lib in TC Sky 20:00:08 |
| | Hi all!
I have a device development library(dev.lib), it can be used successfully
under Borland C++ 3.1 but failed under Turbo C 2.01
TC Error message: "Linker Error: Undefined symbol '_functionname' in module
myfile.c"
So I want to know Is there some library can compatible with BC and TC?
if not, how to convert this library to TC format.
Many thanks in advance.

| [ROOT] Integration of the oscillating function Guest 12:23:38 |
| |
Dear Rooters!
I have to perform a calculation of the integral of oscillating function, namely
J0(z) (Bessel J0). How should I integrate it (in this case the integration is
over "z" variable) in order to obtain a proper result?
For example, in Matematica there is a method of integration which is called
"Oscillatory method" which allows to integrate such oscillating functions.
*I use TF1 class with "IntegralMultiple" function

| [ROOT] rootcint gives: Error: cannot open file "TROOT.h" :0: Oliver Oberst 23:35:09 |
| | Hello,
I am working on a rootinterface for a montecarlo generator. I wrote my
own "HepMCEvent" class which inherits from TObject. Now I want to fill a
Tree with an HepMCEvent Branch with
tree->Branch("EventBranch","HepMCEvent",&event,32000,99);
in my Interface. the header of the Event (for now) is :
----------------------------------------------------------------
#ifndef __HepMCEvent__
#define __HepMCEvent__
#include"TObject.h"
#include "CLHEP/HepMC/GenEvent.h"
class HepMCEvent : public TObject{
public:
HepMCEvent(HepMC::GenEvent *hepmc);
~HepMCEvent();
private:
int event_number;
int signal_process_id;
double alphaQCD;
double alphaQED;
int vertices_size;
ClassDef(HepMCEvent,1) //Event structure
};
#endif
----------------------------------------------------------
if I want to generate a dictionary with rootcint:
promt>rootcint HepMCEventdict.cc -c
-I ../../2.0.2.2/CLHEP/HepMC/include/ -I $ROOTSYS/include/ HepMCEvent.h
i get:
Error: cannot open file "TROOT.h" :0:
!!!Removing HepMCEventdict.cc HepMCEventdict.h !!!
Error: rootcint: error loading headers...
I`m using root 5.13/6. ($ROOTSYS is set correct and TROOT.h is readable
and on the right place)
Thx
