+In this regard, OrcaSong is a project that produces KM3NeT event images based on the raw detector data.
 This means that OrcaSong takes a datafile with (neutrino-) events and based on this data, it produces 2D/3D/4D 'images' (histograms).
 Currently, only simulations with a hdf5 data format are supported as an input.
+
 These event 'images' are required for some Deep Learning machine learning algorithms, e.g. Convolutional Neural Networks.
