SPRING (S ingle P article R econstruction from I mages of kN own G eometry) is a single-particle based helical reconstruction package for electron cryo-micrographs and has been used to determine 3D structures of a variety of highly ordered and less ordered specimens. Spring provides the entire single-particle based work-flow required for helical reconstruction including:
Helical symmetry determination and refinement tools
High-resolution structure refinement
Multi-symmetry structure refinement
