Installing EMAN2

The new EMAN2.2 binaries for recent OS versions are more heavily optimized than previous releases (and less backwards compatible). Still, it may be possible to achieve a 10-20% additional speedup if you setup GCC6 and compile with optimize-machine on a recent Linux version. Compiling from source on Linux is much easier than the other platforms. For Mac and Windows users, we strongly suggest using a binary.

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

 Line 6:
-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 [[http://www.python.org|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.
