Pydidas project

The I2B-project LADIDA - Automatic analysis of large amounts of diffraction data at PETRA III beamlines provided the original funding for the development of the pydidas software package. After the LADIDA project was finished, Hereon's GEMS made pydidas part of its core program.

Motivation


Using X-ray diffraction is essential for material science applications. The capability to deliver „in-situ“ or „operando“ data is necessary to develop digital models and is a key feature of the experiments which are operated by Hereon at the PETRA III beamlines P03 and P07.

Technological developments allow today's detectors (e.g. Dectris Eiger) to run with data rates which are 100 to 1000-fold higher than those which were feasible a few years ago. Only these high frame rates enable investigating fast processes. However, the huge amount of data makes it difficult for users to perform real-time analysis during the experiment. Therefore, users often only know after their experiments if the acquired data has meaningful information. In addition, the large number of frames requires an automatic analysis which might challenge many user groups. A delayed data analysis also delays the preparation of publications, especially for inexperienced user groups.
