[Gate-users] Definition of parameters of new TH2F("DetectPos1", "Transaxial detection position", 252, -504., +504., 252, -504., +504.) in benchPET.c

[신희순]

Hi,

I tried to analyze the results of simulation by using ROOT.
I would like to modify benchPET.c for my simulated system.



I do not know  their definition and how to change as following high lighted
parameters;

1) TH2F *DetectPos1 = new TH2F("DetectPos1","Transaxial detection position",
252,-504.,+504.,252,-504.,+504.);

 2) DetectPos1->Fill(globalPosX1,globalPosY1);

3) if (fmod((double)i,10000.0) == 0.0) cout << ".";
I am wondering whether this is the initial activity.
its activity is  Double_t F18Activity = 100000.


I appreciate if you give any advice.


Thanks!
Heesoon.
