This is a directory to software we distribute freely to the academic community. Our software is concerned with postprocessing of cryo-EM maps and atomic model refinement. Please visit the individual pages for more detail on the programs as well as past and present developments. In addition, there is a collection of useful tools for cryo-EM model building. Currently, all projects are hosted by the EMBL Gitlab instance. If our software or tools are useful for your work, please acknowledge their use.
