Structure refinement and validation for crystallography and single particle analysis.

Servalcat implements pipelines that use Refmac5: - servalcat refine_spa: cryo-EM SPA refinement pipeline - servalcat refine_cx: small molecule crystallography

and a Refmac5 controller - refmacat: behaves as Refmac, but uses GEMMI for restraint generation instead of MAKECIF Now “No Refmac5” refinement programs have been actively developed: - servalcat refine_geom: geometry optimization - servalcat refine_spa_norefmac: "No Refmac" version of refine_spa - servalcat refine_xtal_norefmac: crystallographic refinement

Also, it has several utility commands: servalcat util.
