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
most efficient in terms of measuring diffracted X-rays in all directions. To analyze the single-
crystal diffraction data collected with these detectors, several computer programs have been
developed. Two-dimensional detectors and related software are now predominantly used to
measure and integrate diffraction from single crystals of biological macromolecules …
