📊 DETAILS OF THE DATASET#
🚧🛠️ Under construction 🛠️🚧
There are several different types of datasets that Arrakis will generate from both LArSoft and larnd-sim. On the wire detector side (i.e. LArSoft), there are both one and two-dimensional datasets for the light and charge readout respectively, as well as a three-dimensional dataset for the energy depositions. Each of these datasets contains a set of arrays which maintains the event format, i.e. the first index of each array corresponds to a single event. Each event consists of some set of features (variables) which correspond to the light and charge readout from the event. Depending on the dataset, there are also other arrays which may contain high-level truth information corresponding to each `point’ in an event, as well as for the entire event.
WirePlanePointCloud#
This dataset describes the charge readout from a wire-based LArTPC. Each event is broken up into the corresponding views in the detector, and has the corresponding set of low-level features,
