-If you want to use the EMAN2 python (that is python 2.7), then you can link that python in the FOCUS Preferences dialogue, on **MacOS** for example as  /Applications/EMAN2/bin/python2.7 (or, where-ever you installed EMAN2). +We might not use the tools present in EMAN2 directly, but it is very helpful.

-If you compile FOCUS from source (which is recommended), sure that the ''build_all'' script does not accidentally use the EMAN2 version of qmake. You can test this by typing in a terminal ''which qmake'', or ''qmake ''''-''''-version'', to see, which qmake shows up first in your path. If the EMAN2 qmake is taken first, you might want to rename that to a different qmake name, such as "qmake-4.8.7".+If you compile FOCUS from source (which is recommended), make sure that the ''build_all'' script does not accidentally use the EMAN2 version of qmake.
