The SHELX homepage
SHELX is a set of programs for the determination of small (SM) and macromolecular (MM) crystal structures by single crystal X-ray and neutron diffraction. They are stand-alone executables that require NO libraries, extra files or environment variables. They are compatible with all modern versions of Linux, Windows and MacOSX, and are free for academic use. For-profit users are expected to pay a licence fee that covers development and support for all users.
The programs may be called from a GUI such as shelXle, Olex2, Oscail or WinGX (SM refinement) or hkl2map (MM phasing), or from a command line in a terminal window (for Windows, this is called Command Prompt and may be found in Accessories). Several of the programs output an instruction summary if called without a filename. SHELX-2013 contains the following programs:
SHELXS - Classical direct methods for SM structure solution.
SHELXL - SM and MM refinement, more or less compatible with SHELX76 and SHELXL-97.
CIFTAB and ShredCIF - editing and processing SM CIF files from SHELXL.
SHELXC, SHELXD and SHELXE - MM phasing. SHELXD is also useful for SM direct methods.
AnoDe - preparation and analysis of MM anomalous density maps.
