Dear all, DECTRIS is proud to announce the release of an HDF5 read plugin to take advantage of the recently added XDS plugin support (thanks to Wolfgang Kabsch and Kay Diederichs) and accelerate the reading of HDF5 files.
EIGER detectors produce data in the large-data format HDF5. Despite substantial advantages (few files to handle, excellent compression), HDF5 data pose some difficulties. While DIALS and HKL-2000 process HDF5 data natively, they are limited in their performance by the lack of parallel reading of the HDF library. Processing of HDF5 data by XDS has thus far relied on extraction of temporary CBF images, which adds to the processing time. Neggia, our read plugin for XDS, presents HDF5 data to XDS in a fully parallelized way, directly and without interconversion. Processing of HDF5 data is now as fast as processing of CBFs. Refer to the plugin with LIB= /path/to/plugin.so in XDS.INP. The parameter DETECTOR= EIGER should remain. You can download the plugin from www.dectris.com/neggia.html (registration required). To run it you need a reasonably recent OSX or linux system with gcc 4.8 or higher. We have tested macOS Sierra, CentOS 6, CentOS 7, Mint 17.3. Alternatively, you can compile the plugin from the source available at https://github.com/dectris/neggia. The plugin was written to work with recent EIGER data and has been tested in house and at a few adventurous beamlines. If you encounter issues, please let me now. Your problem reports will help make the plugin better, to the benefit of the entire community.
