Notes about the 31 file extension:



Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).

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.
