Hi,
I’m running the commands in the attached macro as part of a larger project. I have found that the friend tree has a different number of entries in the particle branches after doing AddFriend (it doesn’t happen if I don’t make it a friend of the other tree). It seems like adding the friend reduces the number of entries to that of the first tree.
I was using the same macro for a different set of files and this wasn’t happening, so I suspect It may have something to do with the structure of the new input trees. These trees are generated acording to the pythia8_… macro also attached.
I would appreciate any help on this issue.
