Input and scoring tally storing

Hey everyone!
I would like to have dataset that for each particle stores its starting parameters (position, velocity, …) and if the particle has passed from a user defined tally during its history (lets say a boolean ). Do you think is possibile? I saw just particle track but It seems unecessary for the amount of data that can collect.
Thank you in advance!

Hi @mbelotti and welcome to the community. The only way to get such data is to use the particle track writing feature in OpenMC, which has recently been significantly updated and expanded. The only other way I can think of to get that information would be to modify the source code of OpenMC to write specific information.
