Dear expert, please merge the code

[singhra1994]

Please check o2_hybrid_gen.py and boxgen class, you are blindly using configuration from Run2
There is no boxgenPi or Eta,
This should be boxgen but check variable carefully

"name": "boxgen",
"config": {
"pdg": 111,
"prange": [0.1, 50.0],
"etarange": [-0.8, 0.8],
"phirange": [0.0, 360.0],
"number": 1
}
},
{
"name": "boxgen",
"config": {
"pdg": 221,
"prange": [0.1, 50.0],
"etarange": [-0.8, 0.8],
"phirange": [0.0, 360.0],
"number": 1
}
}
],

okay Thank you for suggestion

No, this is not from Run 2. For this, I ran the following command and it worked properly:
o2-sim -g boxgen -n 1000 -j 1 -o box_out --configKeyValues "BoxGun.pdg=111;BoxGun.prange[0]=0.1;BoxGun.prange[1]=50.0;BoxGun.eta[0]=-0.8;BoxGun.eta[1]=0.8;BoxGun.number=1"

okay i will check variable carefully

Dear @rashigupt , thanks a lot for the works. As mentioned by @singhra1994 , could you please confirm the values of the parameter? Or could you please confirm that number: 1 is what you desired? You can find the meaning of these parameters from https://github.com/AliceO2Group/AliceO2/blob/dev/Generators/include/Generators/BoxGenerator.h

[rashigupt]

Thank you for your comment.
I have checked the parameters, and number = 1 corresponds to the number of particles generated per event in the BoxGenerator.
My intention here is to enhance the statistics for pion and eta at high momentum using a flat distribution in (p). I noticed that the default value is number = 10.
Could you please advise what value of number would be more appropriate if the goal is to increase the statistics while keeping the distribution flat?

Hi @rashigupt , I don't know how to achieve the intention you mentioned. I just think 1 particle per event is too few. I don't think it could help you increase the statistics and flatten the distribution. Since all the implementations are in the config files, I would do some tests to see whether it is helpful and validate the settings
