Interactive graphics for rapid indexing of oscillation films from large unit cells
Paul C. Moews, T. Sakamaki, James R. Knox · Journal of Applied Crystallography · 1986
An interactive graphics program for the Evans & Sutherland PS330 has been written to display and index screenless X-ray oscillation films from macromolecular crystals with unit-cell edges of at least 500 Å. ALIGN, a Fortran program which works in conjunction with M. G. Rossmann's program OSCMGR, accurately displays densitometered reflection intensities, provides the required transformation between predicted and observed reflection coordinates, and is useful in determining crystal mosaicity and detecting unit-cell changes.
