Recent Software Updates:

Name Description
Frealign (Fourier REconstruction and ALIGNment) a program for high-resolution refinement of 3D reconstructions from cryo-EM images of single particles. A GPU-enabled version is also available. Developed by Niko Grigorieff at Brandeis University.
HKL2000 A data processing suite for X-ray crystallography that provides a sleek interface for devising a data collection strategy and processing data. HKL is based on the extended versions of Denzo, Xdisplayf and Scalepack.HKL was developed and is maintained by Wladek Minor (University of Virginia).
IMOD A set of image processing, modeling and display programs used for tomographic reconstruction and for 3D reconstruction of EM serial- and optical sections. The package contains tools for assembling and aligning data within multiple types and sizes of image stacks, viewing 3-D data from any orientation, and modeling and displaying the image files.
PDB_REDO PDB_REDO refines any structural model you are working on, by optimising REFMAC refinement and by partial model rebuilding. The process is fully automated so you only need to provide an initial structure model and your reflection data.
PDBstat Is a C/C++ computer program originally developed as a universal coordinate and protein NMR restraint converter. Its primary function is to provide a user-friendly tool for interconverting between protein coordinate and protein NMR restraint data formats.
