Crystallography Laboratory University of Nijmegen
A computer program system for crystal structure determination by
Patterson methods and direct methods applied to difference structure factors.
The programs are available for a wide range of computer and operating systems. They have
been tested and used on IBM/cms, VAX/VMS, CYBER computer, PC (PCDOS, MSDOS)
and various unix systems (Silicon Graphics, SunOS, Solaris, DEC, Alpha, HP, linux, IBM/AIX).

In principle the system is free of charge for non-commercial users, but
because of the increasing costs of the distribution of the DIRDIF
program system, the university administration has asked me to request
some payment for file handling, printing, mailing costs, etc.
If you have no funds available, please, don't hesitate to tell me.
Please, get the DIRDIF system implemented, see that all test
examples work well, and inform us on your implementation!
