FUNCTION KEYWORDS & INPUT REQUIREMENTS
 The sequence of function keywords determines the sequence of running options.
 For simplicity, all input should include cell, symmetry, number_wavelength,
  group and resolution. Optional global parameters include print, list.
 ABSOLUTE (B. Weis/H. Wu): Calculate expected signal, absolute rmsF and 
     relative scales among the different wavelengths.
   obligatory: infile, name, fp, fpp, scat, copy, bover, sequence 
 ANOMERGE (H. Wu/M. Cuff): Bijevot differences are averaged among data from 
     all the wavelengths for calculating Bijevot difference patterson. 
   obligatory: infile, fpp
   optional: outfile, fcut, rmsdel, anocut
 ANORES (W. Hendrickson): Calculate anomalous signals present in data of each 
     wavelength. 
   obligatory: infile
   optional: shell, anocut, fcut
 ANOSCL (W. Hendrickson/B. Weis/H. Wu): Parameterized anisotropic localing 
     scaling is performed to reduce noises in Bijevot difference.
   obligatory: infile, local
   optional: outfile, dffcut, anocut, rmsdel, fcut
 ASLSQ (W. Hendrickson/H. Wu): Refine anomalous scatterer sites against fa.
   obligatory: infile, scat, atom, refine
   optional: outfile, cycles, cutoffs(facut, famax, pmax), shell, fcscale, 
     weighting
 F2ANO (H. Wu/B. Weis): Observations related by a certain data collection 
     geomoetry are paired. In addition, symmetry and centric/acentric codes 
     are calculated and intensities changed into amplitudes.
   obligatory: infile, mirror/inverse/random, batch_group, format
   optional: outfile
 FA: FA consists of a series of functions to generating fa: F2ANO,ANOSCL,
   WVLSCL,MADLSQ AND MERGIT. 
 MADABCD (H. Wu/Ano Paler): Calculating Hendrickson/Lattman phase coefficients 
     based on anomalous scatterer model. This is not only useful for phase 
     combination but should also prove superior to madfaz in generating protein 
     phases in that it generally phases more reflections and gives more 
     realistic figure of merit.
   obligatory: infile, scat, fp, fpp, fcscale, atom
   optional: outfile, xplor, cutoffs(facut, fzcut, faflag, fcut, famax, fzmax, 
     famin, pmax, qmax), shell, franges, mode, nstep, step, anoblock, block
 MADFAZ (W. Hendrickson/H. Wu): Phiz is calculated from Delphi and Phia from 
     input anomalous scatterer model to complete MAD phasing by outputing FZ, 
     Phiz, fom.
   obligatory: infile, scat, fcscale, atom
   optional: outfile, xplor, output, cutoffs(famax, famin, acut)
    f.o.m = cos(sigma(phi))
    f.o.m = 0.0 for those reflections with FA > famx or fa < famin 
    f.o.m = min(f.o.m, fa/sa/acut) for those reflections with FA < acut*sa
 MADLSQ (W. Hendrickson/B. Weis/H. Wu): Least-squares solutions to the MAD 
     equation are performed for each observation, where FA, Delphi and FZ are 
     derived.
   obligatory: infile, scat, fp, fpp, scale, fit
   optional: outfile, output, linear, anoblock, block, iteration, skcut,
     cutoffs(famax, fzmax, facut, fzcut, pmax, qmax)
 MERGIT (J. Smith/H. Wu): Individual observations are merged to give weighted 
     FA, Delphi, FZ.
   obligatory: infile
   optional: outfile, xplore, shell, cutoffs(famax, facut, fzcut, pmax, qmax)
 PHASE: Also know as MADABCD. 
 WVLSCL (J. Smith/H. Wu): Overall and parameterized anisotropic local scaling 
     are performed between data from different wavelengths.
   obligatory: infile, absf, wave_local
   optional: cutoffs(fcut, rmsdel, dispcut), observations
