A new release (version 7.3.0) of the data processing program iMosflm is now available for the MRC website: https://www.mrc-lmb.cam.ac.uk/mosflm/imosflm <https://www.mrc-lmb.cam.ac.uk/mosflm/imosflm>
The most significant difference to the previous version (7.2.2) is the ability to read Dectris HDF5 files directly, rather than having to convert them to CBF files (using eiger2cbf). These changes were implemented by Harry Powell (now an independent software consultant) with financial support from Dectris, Diamond Light Source and CCP4. When reading HDF5 files, there is the option to sum images prior to processing, which may give improved performance if the oscillation angle is very small. Images from the new Dectris Eiger2 and Dectris Quadro detectors and Rigaku Pilatus and Eiger image formats are also handled. A bug in version 7.2.2 meant that MTZ files produced when using the multi lattice integration option could not be read correctly by any downstream programs (POINTLESS etc). this has been corrected. There have also been minor changes to the integration of very weak images (where many pixel values are zero) to avoid bias in the intensity estimation. There have been numerous additional minor improvements and bug fixes, a full list is given on the web site (Under “changes since 7.2.2"). The reading of HDF5 format images has been tested with files from ESRF and Diamond Light Source. Because there is not yet a universally agreed format for the header information, there may be issues with reading the metadata (phi values, detector distance, wavelength etc) from files produced elsewhere, please let me know if this is the case. This latest version will be released as part of the CCP4 package in due course.
