Integration of macromolecular diffraction data.
Diffraction intensities can be evaluated by two distinct procedures: summation integration and profile fitting. Equations are derived for evaluating the intensities and their standard errors for both cases, based on Poisson statistics. These equations highlight the importance of the contribution of the X-ray background to the standard error and give an estimate of the improvement which can be a...
متن کاملThe integration of macromolecular diffraction data.
The objective of any modern data-processing program is to produce from a set of diffraction images a set of indices (hkls) with their associated intensities (and estimates of their uncertainties), together with an accurate estimate of the crystal unit-cell parameters. This procedure should not only be reliable, but should involve an absolute minimum of user intervention. The process can be conv...
متن کاملEfficient use of synchrotron radiation for macromolecular diffraction data collection.
In recent years, number of X-ray synchrotron beam lines dedicated to collecting diffraction data from macromolecular crystals has exceeded 50. Indeed, today most protein and nucleic acid crystal structures are solved and refined based on the synchrotron data. Collecting diffraction data on a synchrotron beam line involves many technical points, but it is not a mere technicality. Even though the...

متن کاملThe design of macromolecular crystallography diffraction experiments
The measurement of X-ray diffraction data from macromolecular crystals for the purpose of structure determination is the convergence of two processes: the preparation of diffraction-quality crystal samples on the one hand and the construction and optimization of an X-ray beamline and end station on the other. Like sample preparation, a macromolecular crystallography beamline is geared to obtain...
