2dx is an initiative that aims to facilitate computer image processing in electron crystallography. Electron crystallography is our method of choice for the determination of the high-resolution structure of membrane proteins in the membrane-embedded state. It is done by recording cryo-electron microscopy images of two-dimensional membrane crystals of the membrane proteins, and reconstructing the 3D structure of the proteins by computer image processing of a larger number of images.
We have created a software package called 2dx that aims to provide the user with user-guidance and help, and features streamlined processing solutions with optional full automation. This site is the home of the 2dx software, and hosts the software itself, including the open source code, as well as the manual, that the users can annotate in blog form.
