As discussed in the tutorial, you can calculate a global cross correlation
between your structure and your density map using 'mdff check' or mdff
'ccc'. This value will give you an idea of the quality of fit. You can also
use Timeline to calculate many local cross correlations which will provide
a finer level of analysis. Using Timeline for cross correlation is
discussed in the last section of the mdff tutorial.
