Description (last modified by Pavel Demin)

Hello, I am Nam

Now I am trying to read fUniqueID.

Actually, I would like to read Mother particles information, in the macro, when I require like this

GenParticle *part = (GenParticle*) branchParticle->At(multi);)
cout<<part.M1<<endl;

I receive the number or barcode, I guess, this is related with fUniqueID.
So, I would like to check GenParticles Mother particles.

Do you have any idea? Could you help me?

Hello Nam,

part.M1 is an array index of the mother particle. So, accessing the mother particles can be done with the following code:

GenParticle *mother = 0;
GenParticle *part = (GenParticle*) branchParticle->At(multi);
if(part.M1 >= 0) mother = (GenParticle*) branchParticle->At(part.M1);

Best regards,

Pavel
