Hi All, While we're on the matter of using Python to access the information in the image, I thought I should mention the Diffraction Image library maintained by Francois Remacle. http://www.ccp4.ac.uk/newsletters/newsletter45/articles/DiffractionImage .html This is a general purpose library for accessing information in diffraction images of many formats including CBF. Although the API is more limited (as it has to be general) the key items describing the experiment are available. At the moment we're just ironing out a small problem with the CBF reading, in that one of the beam centre ordinates comes out negative. I'm not sure if this is a problem with the example image or the library, but I can see the beam centre in the middle of the picture... Has anyone seen this problem before? Anyhow, I just thought I would give this a mention. This is a C++ library with bindings to both Tcl and Python, again through swig.

The bindings are generated by SWIG and give access to many, but not all, of the functions in CBFlib from python. Assuming you've got CBFlib already then the download should just add pycbf directory to your CBFlib source tree, eg: % cd CBFlib % make -f Makefile_Linux all % make -f Makefile_Linux tests % # CBFlib is now up-to-date % wget http://blondie.dowling.edu/frs/download.php/297/pycbf.tar.gz % tar -zxf pycbf.tgz % cd pycbf % python setup.py build % # your platform might be different % cp build/lib.linux-i686-2.4/_pycbf.so . % python pycbf_test1.py % python pycbf_test2.py % python pycbf_test3.py Any feedback would be most welcome!
