(Crystallographic Object-Oriented Toolkit) supports model building and real space refinement. This application interfaces with refmac, Phenix, and several other applications. Coot was recognized as the best structural biology application in 2008 by SBGrid.

a software suite for modeling macromolecular structures and for predicting and designing protein structures, protein folding mechanisms, and protein-protein interactions.

(REgularised LIkelihood OptimisatioN) a stand-alone computer program for Maximum A Posteriori (MAP) refinement of (multiple) 3D reconstructions or 2D class averages in cryo-electron microscopy.

an open source Message Passing Interface implementation that is developed and maintained by a consortium of academic, research, and industry partners. Open MPI is therefore able to combine the expertise, technologies, and resources from all across the High Performance Computing community in order to build the best MPI library available.

a multi-GPU program that corrects beam-induced sample motion on dose fractionated movie stacks. It implements a robust iterative alignment algorithm that delivers precise measurement and correction of both global and non-uniform local motions at single pixel level across the whole frame, suitable for both single-particle and tomographic images.

a novel automated particle picking software based on the deep learning object detection system 'You Only Look Once' (YOLO). CrYOLO is available as standalone program under http://sphire.mpg.de/ and will be part of the image processing workflow in SPHIRE.

a highly extensible, interactive molecular graphics program for interactive visualization and analysis of molecular structures and related data, including density maps, supramolecular assemblies, sequence alignments, docking results, trajectories, and conformational ensembles. It is often a tool of choice for rendering EM volumes.
