This is a fork of the orginal eiger2cbf written by Takanori Nakane. This version contains mods for the NSLS-II MX beamlines.
eiger2cbf is a simple program that converts diffraction images from EIGER in the HDF5 format to the miniCBF format. This program is intended to be used with MOSFLM. You do not need this program to process images with DIALS; DIALS can process HDF5 images directly (DIALS 1.2.0, which comes with CCP4 7.0.13).
You can get static-linked binaries built by Harry Powell from his website. See the bottom of the iMosflm download page. Note that the binaries are not necessarily the latest version (160415).
To build yourself, you should edit Makefile and run make.
Running eiger2cbf without command line options shows a help.
$ eiger2cbf
EIGER HDF5 to CBF converter (build 160310)
Written by Takanori Nakane
Usage:
./eiger2cbf filename.h5 -- get number of frames
./eiger2cbf filename.h5 N out.cbf -- write N-th frame to out.cbf
./eiger2cbf filename.h5 N -- write N-th frame to STDOUT
./eiger2cbf filename.h5 N:M out -- write N to M-th frames to outNNNNNN.cbf
N starts from 1. The file should be "master" h5.
The command line option is almost the same as H5ToXds from Dectris. Actually, you can use eiger2cbf instead of H5ToXds. This might be useful on Mac OS X because H5ToXds is provided only for Linux (as of 2016 Feb). In this case, you may want to create the following wrapper script named H5ToXds.
#!/bin/sh
# redirect STDERR to /dev/null so that it does not disturb console outputs from other programs.
/path/to/eiger2cbf $@ 2>/dev/nullI believe that eiger2cbf is fast enough for offline processing but if you are impatient, you might want to write a small wrapper script to launch multiple instances of eiger2cbf for each subset of a dataset (e.g. image 1 to 100, 101 to 200 and so on). Probably disk and/or network IO will be the next bottleneck.
Online processing on a high performance storage is another story. Here, eiger2cbf can be a bottleneck. If there is really a demand, I am happy to help. Post a feature request on the Issues page.
H5ToXds from Dectris and hdf2mini-cbf from Global Phasing have similar capacities. The advantage of eiger2cbf is that it is open-source, free software. The others are closed-source. MOSFLM cannot process outputs from H5ToXds because they lack essential headers.
The program reads the pixel mask from the master H5 file and apply it to the image. When the mask is 1, it outputs -1. When the mask is 2, 4, 8 or 16, it outputs -2. Otherwise, the program outputs the original value as is.
If the pixel mask is not available, the program assumes that the pixel mask has already been applied to the images. The values of the invalid pixels (65535 if the image is 16-bit) are converted to -1 (as in Pilatus). However, this might also mask heavily saturated pixels. Fortunately, most datasets contain the pixel mask in the master H5 file.
The following metadata are converted from the master h5.
- Detector name and serial number
- Pixel size
- Sensor thickness
- Countrate correction cutoff
- Wavelength
- Detector distance
- Beam center
- Exposure time
- Exposure period
- Start angle
- Angle increment
Unfortunately, some of them are missing in some datasets. In these cases, the converter outputs zero or standard (common) values. See the console output. In the future, we will add command-line options to supply metadata.
Warning: currently, we assume the rotation is around the 'omega' axis and two-theta is 0. Send me test data if you need support for more complex geometry.
The program has been tested on the following datasets.
- EIGER 16M at SLS X06SA (2016 Feb)
- EIGER 4M at ESRF ID30A-3
- EIGER 4M and 16M sample datasets on Dectris website (downloaded in 2015 Nov)
- EIGER 9M at SPring-8 BL32XU (2016 May)
As there are many beamline and firmware-version specific "dialects", eiger2cbf might not work on your dataset. If the program does not work well, feel free to contact me from the "Issues" page. If you can give me test datasets, it would be very helpful!
I thank Harry Powell for writing Makefile, fixing compiler warnings and building & hosting binaries. I thank those who gave me feedback and test datasets.

eiger2cbf includes bitshuffle and lz4 HDF5 plugin, both of which are also licensed under the BSD license. See LICENSE files in bitshuffle and lz4 directories.
eiger2cbf also depends on HDF5 library and CBFlib. See LICENSE.HDF5 and LICENSE.CBFlib. Both are included in this source distribution.
As of September 2020, there are two ways in which to adapt eiger2cbf to MS Windows 10, use WSL2 Ubuntu or use MSYS2. WLS2 Ubuntu provides full support for all eiger2cbf features, but requires that the WSL2 Ubuntu subsystem have been installed first, making installation on older Windows 10 systems problematic. The MSYS2 version has more limited feature support, but allows to creation of an NSIS installer that can be used to install the eiger2cbf program as eiger2cbf.bat, but not of the plugins.
You only should need the exe in the release downloads. That exe is a NSIS installer that will install a folder with the necessary files in a folder you select and a file named
eiger2cbf.bat
in C:\Windows and define an environment variable to find the folder you selected. You should not need to add anything new to your path
Since C:\Windows is in the default path for command windows (cmd), you should be able to run it in any command window.
If you just run
eiger2cbf.bat
you should get the help message.
If you have an hdf5 master file, say, c:\myfiles\mydata_master.h5 and want the cbfs of frames 37 through 48, then
eiger2cbf.bat c:\myfiles\mydata_master.h5 37:48 mycbfs_
should give you those cbfs.
