====MAP LEVELS====
* Generally speaking there is some ambiguity with visualization tools as to how map data is to treated:  Some map file formats are normalized by convention (in the file data itself) and others do not.  Some visualization tools automatically normalize maps upon reading, others do not.  PyMOL's default behavior is dependent upon map file type: CCP4 and O/BRIX/DSN6 maps are automatically normalized upon reading (disable via '''normalize_*''' settings), other maps types are not.  PyMOL's normalization is a straight statistical average of all map points -- this may or may not be what you want.   If migrating to PyMOL from another tool, then it is definitely worth comparing how the maps are being represented by creating an equivalent figure in both, making sure that they match, and if they do not, then figuring out why not.
