The various physical factors affecting measured diffraction intensities are discussed, as are
the scaling models which may be used to put the data on a consistent scale. After scaling …

Serial crystallography, using either femtosecond X-ray pulses from free-electron laser
sources or short synchrotron-radiation exposures, has the potential to reveal metalloprotein …

Following integration of the observed diffraction spots, the process ofdata reduction'initially
aims to determine the point-group symmetry of the data and the likely space group. This can …

This paper presents an overview of how to run the CCP4 programs for data reduction
(SCALA, POINTLESS and CTRUNCATE) through the CCP4 graphical interface ccp4i and …

Important steps in the processing of rotation data are described that are common to most
software packages. These programs differ in the details and in the methods implemented to …

Publisher Summary X-ray data can be collected with zero-, one-, and two-dimensional
detectors, zero-dimensional (single counter) being the simplest and two-dimensional the …

The F-actin filament has been constructed from the atomic structure of the actin monomer to
fit the observed X-ray fibre diagram from oriented gels of F-actin. A unique orientation of the …

Directed movement is a characteristic of many living organisms and occurs as a result of the
transformation of chemical energy into mechanical energy. Myosin is one of three families of …

X-ray diffraction images from two-dimensional position-sensitive detectors can be
characterized as thick or thin, depending on whether the rotation-angle increment per image …

A novel and general approach to scaling diffraction intensities is presented. The method
minimizes the disagreement among multiple measurements of symmetry-related reflections …
