Hi All,

I have to do radiation length analysis as a part of my work,for that I have followed following link which is suggested by Artem Basalaev in the forum.

https://forum.gsi.de/index.php?t=msg&goto=13440&rid=1765&S=5 3e3e1de6f2611aad37bcc2a6e0ddda2#msg_13440

Initially I had some error related TGeoManager looked like as

Error: illegal pointer to class object geoman 0x0 2423

Than I read some discussion on similar topic at link:-
https://forum.gsi.de/index.php?t=msg&goto=10664&rid=1765&S=5 3e3e1de6f2611aad37bcc2a6e0ddda2&srch=geoMan#msg_10664

And added parameter file in ana macro as instructed in discusssion. but after this I have another problem which I could not solve.
Error msg is like as:-

Root > Function radanaduplicate() busy flag cleared

Can anybody tell me what I should do to correct it?
I have attached my analysis macro here.

Thanks in advanse

Hallo Ajay,

In your macro you have:

....

Quote:

TFile* f = new TFile(inFile.c_str()); // the sim file you want to analyse
TTree *t=(TTree *) f->Get("cbmsim") ;

TFile* file = new TFile("Simulation_par.root");
file->Get("FairBaseParSet");
TClonesArray* mc_array=new TClonesArray("PndMCTrack");
t->SetBranchAddress("MCTrack",&mc_array);//Branch names
TClonesArray* rad_array=new TClonesArray("FairRadLenPoint");
t->SetBranchAddress("RadLen",&rad_array);
// TGeoManager *geoMan = (TGeoManager*) gDirectory->Get("FAIRGeom");
TGeoManager *geoMan = (TGeoManager*) gDirectory->Get("FairBaseParSet");
// PndGeoHandling* fGeoH = new PndGeoHandling();
...

You do not need to call the line in RED it is even wrong, when you call

file->Get("FairBaseParSet");

the geometry is read in memory and the "gGeoManager" global pointer is valid, just use it and it should work! Simply remove the line in RED and use directly gGeoManager, i.e:

TGeoNode* node = gGeoManager->FindNode(point.x(),point.y(),point.z());

regards,

Mohammad
