PyPhase is an open-source code for phase retrieval from in-line (propagation based, Fresnel diffraction) phase-contrast images. Its main aims are to provide

• A flexible phase-retrieval toolbox for expert users

• High level of modularity to facilitate the integration of different functionality, e.g., registration, tomography, Fast Fourier Transform, reading and writing data, and visualization.

• Tools for deployment on computer clusters and heterogeneous computing infrastructures

• Tools for implementation and development of phase retrieval algorithms

• Command-line interface and graphical user interfaces, for non-expert users

The aim of this workshop is to give an introduction to the PyPhase package, its implementation philosophy, usage, and how to contribute, as well as to give support for installation and initial use as well as application. Participants are expected to bring their own data to start data analysis using PyPhase. Problems, requests, and future directions will be collected and discussed.

The workshop will be hybrid. The registration for physical participation is now closed but you can still register for digital attendance.
