scale density scale factor line
solden solvent density value line
fzovol1 base electron density value line
sratio1 base electron density ratio line
1 Only one or the other is used, not both.
APMASK process solvent density
avgden set to average solvent density
nonneg replace -ve value in molecule region with 0
scale scale applied to density values within non-solvent regions 1.
solden value assigned to all solvent densities in resulting map 0.
Will not be used if avgden has been specified on APMASK line.
fzovol 1 F-zero/volume value used as an additive offset to all densities except solvent density in the case of the solden option 0.
sratio non-zero value causes fzovol to be calculated and applied to all densities in the map
