Abstract
The image-processing system SPIDER has been designed to operate on a minicomputer in a multiuser environment. SPIDER, which can be run either interactive or batch mode, makes a wide range of operations (including contrast enhancement, Fourier filtration, correlation averaging, and three-dimensional reconstruction) available for analysis of electron micrographs. The command language supports a hierarchical calling structure, branching commands, and DO-loops similar to those of FORTRAN.
