Abstract

The specification of the information on the three-dimensional orientation of an image with respect to a given coordinate system is at the heart of our ability to reconstruct a three-dimensional object from sets of its two-dimensional projection images. Transferring this information from one package to another is important to structural biologists wanting to get the best from each software suite. In this chapter, we review in depth the main considerations and implications associated with the unambiguous specification of geometrical specifications, in this way paving the way to the future specifications of standards in the field of three-dimensional electron microscopy. This is the case of EMX in which affine transformations have been adopted as the means to communicate geometrical information.
