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. These stand-alone executables 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-2015 contains the following programs:

SHELXT - New small molecule (SM) structure solution program.

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.

All the talks from the SHELX Workshops at the 2014 IUCr Congress in Montreal may now be found under 'SHELX Workshops'. I am very grateful to all the speakers for these contributions.
