File Extension 31

File type: Phased Structure Factor File

The 31 file type is primarily associated with 'PHASES'. PHASES is a package of computer programs designed to compute phase angles for diffraction data from macromolecular crystals. The programs are written in FORTRAN 77 with the exception of a single C interface subroutine (facilitating use of X-Window graphics in some programs) and are applicable to any space group without requiring changes by the user. The program package was written by W. Furey, VA Medical Center and University of Pittsburgh, Dept. of Crystallography. Documentation dates from 1997.

When windows gives you an error message saying that it
"Cannot open 31 files", this means either:

A. You need to identify a program that can open the file
B. Or your registry may be damaged

In both cases it is strongly recommended that you
run a free scan for registry errors.
