scipp is a software stack developed at ESS with in-kind contributions from ISIS for the reduction of neutron scattering data. It consists of multiple Python libraries:

  • scipp: General purpose multi-dimensional arrays with labelled dimensions, physical units, and support for non-destructive binning of event data.
  • scippnexus: Low-level utilities for reading and writing NeXus files.
  • scippneutron: Cross-facility routines for neutron data reduction.
  • ess: Functionality bespoke to ESS.

scipp's lean and flexible data structures allow it to scale to larger data than other software. In addition, its high-level design prevents many common mistakes and makes scipp accessible to people with little programming experience.
