SHELX is a system of programs for macromolecular users supporting crystal structure determination. SHELX originally regarded small molecules only, but it is now upgraded to be used also for macromolecules. SHELX includes: SHELXS Structure solution, SHELXC Preparations of files for macromolecular phasing, SHELXD Structure solution, SHELXE Phases, SHELXL Structure refinement, CIFTAB Tables, SHELXA Post-absorption corrections, […]
