CBFlib 0.9.2.2 is a minor revision to the CBFlib 0.9.2.1 release in July 2011 to update doc/cif_img.dic to the 1.6.4 revision.
CBFlib 0.9.2.1 is a minor revision to the CBFlib 0.9.2 release in June 2011 to upgrade the setup script for the pycbf Python bindings to simplify using pycbf outside the context of the CBFlib pycbf directory.
CBFlib 0.9.2 is the recommended release of CBFlib of February 2011. The commulative changes in releases 0.9.1 and 0.9.2 since CBFlib 0.9.0 are:
CBFlib 0.9.1 included a correction to CBFlib 0.9.0 to make axis the cbf_simple routines apply axis rotations correctly for detectors and to pick up corrections for byte offet compression incorporated into the upcoming CBFlib 0.9.1 release. The earlier version had failed to apply the rotations to the accumulated displacements. Our thanks to Joerg Kaercher of Bruker-AXS for identifying the rotation problem.
CBFlib 0.9.0 was a partial pre-release of CBFlib version 0.8 needed to support changes in RasMol. This release was incomplete and used were advided to use it with caution, but it has proven to be a reliable, stable release for 2 years. There have been significant changes in the input/output logic and in validation. For a ChangeLog consult the SVN of the CBFlib project on sourceforge.
CBFLIB is a library of ANSI-C functions providing a simple mechanism for accessing Crystallographic Binary Files (CBF files) and Image-supporting CIF (imgCIF) files. The CBFLIB API is loosely based on the CIFPARSE API for mmCIF files. Starting with this release, CBFLIB performs validation checks on reading of a CBF. If a dictionary is provided, values will be validated against dictionary ranges and enumerations. Tags missing under parent-child relationships or category key requirements will be reported. CBFlib provides functions to create, read, modify and write CBF binary data files and imgCIF ASCII data files.
CBFLIB should be built on a disk with at least 350 megabytes of free space, for a full installation with complete tests. Read the instructions below carefully, if space is a problem.
A gizpped tarball of this release is available on sourceforge at
In addition, http://downloads.sf.net/cbflib/CBFlib_0.9.2_Data_Files_Input.tar.gz (13 MB) is a "gzipped" tar of the input data files needed to test the API, http://downloads.sf.net/cbflib/CBFlib_0.9.2_Data_Files_Output.tar.gz (34 MB) is a "gzipped" tar of the output data files needed to test the API, and, if space is at a premium, http://downloads.sf.net/cbflib/CBFlib_0.9.2_Data_Files_Output_Sigs_Only.tar.gz (1KB) is a "gzipped" tar of only the MD5 signatures of the output data files needed to test the API. Place the CBFlib_0.9.2.2.tar.gz file in the directory that is intended to contain up to 4 new directories, named CBFlib_0.9.2.2 (the "top-level" directory), CBFlib_0.9.2_Data_Files_Input and either CBFlib_0.9.2_Data_Files_Output or CBFlib_0.9.2_Data_Files_Output_Sigs_Only. If you have wget on your machine, you only need to download the source tarball. If you do not have wget, you will need to download all the tarballs into the same directory
Uncompress CBFlib_0.9.2.tar.gz with gunzip and unpack it with tar:
gunzip CBFlib_0.9.2.tar.gz tar xvf CBFLIB_0.9.2.tar
To run the test programs, you will also need Paul Ellis's sample MAR345 image, example.mar2300, Chris Nielsen's sample ADSC Quantum 315 image, mb_LP_1_001.img, and Eric Eikenberry's SLS sample Pilatus 6m image, insulin_pilatus6m, as sample data. In addition there are is a PDB mmCIF file, 9ins.cif, and 3 special test files testflatin.cbf, testflatpackedin.cbf and testrealin.cbf. All these files will be dowloaded and extracted by the Makefile from CBFlib_0.9.2_Data_Files_Input. Do not download copies into the top level directory.
After unpacking the archives, the top-level directory should contain a makefile:
|Makefile||Makefile for unix|
and the subdirectories:
|src/||CBFLIB source files|
|include/||CBFLIB header files|
|bin/||Executable example programs|
|examples/||Example program source files|
|html_images/||JPEG images used in rendering the HTML files|
|lib/||Compiled CBFLIB (libcbf.a) and FCBLIB (libfcb.a) libraries|
|m4/||CBFLIB m4 macro files (used to build .f90 files)|
|mswin/||An MS Windows CodeWarrior project file|
|pycbf/||Jon Wright's Python bindings|
and additional Makefiles for other systems. All the makefiles are created from m4/Makefile.m4. Edit the closest approximation to your system, and then copy that variant to Makefile.
For instructions on compiling and testing the library, go to the top-level directory and type:
Once you have a properly configure Makefile, compile and test the package with
