Compiling and Installing EMAN2

Most users, even 'advanced' users should select a binary install. If the binaries don't work for you for some reason (please let us know, or if you need to write new low-level image processing functions, then you can resort to a source-based installation.)

EMAN2 uses an increasingly popular approach of writing all of the main computationally intensive image processing operations in C++, but writing all of the user programs, including those with GUIs (graphical user interfaces) in a scripting language called Python. All of these Python level programs can be edited by the end-user WITHOUT requiring a C++ development environment. Note that most users won't want or need even this level of customization.
