MergeCluster

Plugin Description

Plugin that merges energy deposits with the same cluster index into a single interaction.

The 3D postiion is calculated as the energy weighted average of the 3D positions of the energy deposits. The time of the merged cluster is calculated as the energy weighted average of the times of the energy deposits. The energy of the merged cluster is the sum of the individual energy depositions. The cluster is then classified based on either the first interaction in the cluster or the most energetic interaction.

Config Options

Option	default	track	Help
debug	False	False	Show debug informations
deterministic_seed	True	True	Set the random seed from lineage and run_id, or pull the seed from the OS
tag_cluster_by	take://resource://SIMULATION_CONFIG_FILE.json?fmt=json&take=tag_cluster_by	True	Decide if you tag the cluster according to first interaction (time) or most energetic (energy) one
user_defined_random_seed	None	True	Define the random seed manually. You need to set deterministic_seed to False
