 = Less efficient way of processing Eiger data, using conversion to CBF=
-Since the release of Neggia, a plugin for XDS that parallelizes the reading of images from HDF5 data, conversion to H5ToXds should no longer required in most usage scenarios. The sections below nevertheless describe this possibility, since preliminary experience with some less common network file systems (apparently GPFS, but not NFS) seems to indicate low performance of Neggia.

 Conversion program options: Dectris provides [https://www.dectris.com/news.html?page=2 H5ToXds] (Linux only!). That program converts (as the name indicates) the HDF5 files to CBF files; however, it does not write the geometry and other information into the CBF header (therefore, [[generate_XDS.INP]] or MOSFLM does not work with these files). Alternatives are GlobalPhasing's hdf2mini-cbf program (needs autoPROC license) or, from http://www.mrc-lmb.cam.ac.uk/harry/imosflm/ver721/downloads, the eiger2cbf-osx or eiger2cbf-linux program written by T. Nakane. The latter programs do write a useful CBF header.
