Sample input files are available giving a reasonable sequence of refinement steps. The program is then ready to process the next image in the series. Autoindexing need be performed only once per series, but some refinement is done for each image before it is integrated. It determines relative scale factors between the images, can post-refine cell parameters, mosaicity, and crystal orientation, computes Rsym's, and merges the data into a single set of h, k, l, F2, and sigma. Miscellaneous ancillary routines.
Users are also welcome to temporarily install their favorite programs.
Fortran, c, and X windows are available. The window management system is Motif on the Alphas and DECwindows on the DECstation. The Fuji scanners have a readout time of about 90 seconds. The CCD detector betters this time by a factor of four. With typical exposure times of a few seconds, an on-line system needs to be able to process an image in less than 30 seconds in order to keep up.
