of the workshop is to bring together developers and practitioners of ptychography to assess the current landscape of available algorithms and software, investigate commonalities and discuss a range of topics, from required theoretical and algorithmic advancements and unmet needs on through to practical issues of implementation and deployment. 
1) Ptycho / Tomo  Software solutions: Descriptions, demonstration and presentation of existing (and future) reconstruction solutions.
2) Workflows: Discussion of end-to-end pipelines for ptychography data acquisition, storage, transmission and processing. Mainly focusing software and architecture.
3) Algorithms: Phase retrieval, Illumination retrieval, Tomography, Multi-slice, Partial coherence, Background retrieval, drifts, phase unwrapping, fluctuations, structured illumination, and so on.
1) Data Bank: The goal is to build a new open-access repository of ptychographic datasets that can be used as a reference by the community. Stimulate commitment /usage via publication with the widest possible participation.
2) Data Format: Design and agree on a common standard or data exchange for ptycho(-tomo) datasets with the biggest possible consensus across institutions, scientists and developers. Similar strategy as with the data bank.
3) Benchmarks: Develop a benchmark reference framework to assess the performance of ptychography algorithms and solutions.
The ultimate goal of this workshop is to compare notes and open/enhance collaboration channels that could benefit all the ptychography community.
