Welcome to the Wiki of the Data Handler P(aris). The Data Handler P was developed at the CNRS Laboratory for Molecular and Structural Archaeology (LAMS, UMR 8220) at the Sorbonne University in Paris (FR) in by Matthias Alfeld in collaboration with Philippe Walter, Laurence de Viguerie, Marie Radepont and Silvia Pedetti. Later, the code was revised and refined at the German Particle Accelerator (DESY, Hamburg, DE) and TU Delft (NL) by M. Alfeld.

The different components were developed for different projects, often on an ad hoc basis. This release unifies them and adds a workflow/pipeline generator that lets users not well versed in programming define and adjust them.

This Wiki assumes the reader to isbe already familiar with Multivariate Analysis and imaging spectroscopy.

An updated YOUTUBE tutorial series is also available.
