1. Obtaining fa for determination of anomalous scatterer sites.
    F2ANO --> (ANOSCL) --> WVLSCL --> MADLSQ --> MERGIT
    also called FA.
 2. Refining sites.
    aslsq
 3. Obtaining protein phases.
    MERGIT --> MADFAZ or 
    WVLSCL, MADLSQ --> MADABCD (PHASE)
 The 1, 2, 3 above comprise the major steps of a structure determination. 
 4. Obtaining parameters for inputting into wvlscl and madlsq.
    absolute
 5. Obtaining averged delta(F) for anomalous difference patterson.
    F2ANO --> (ANOSCL) --> ANOMERGE
 6. Obtaining statistics on the presence of anomalous signal.
    F2ANO --> (ANOSCL) --> ANORES 
    
  One can stop and start at any point.
