If reading, the eigenvalues and eigenvectors of the atomic Hessian are read from the file generated by a previous run, rather than calculated. This option must be used with the job that generated the eigenfile and the job reading the eigenfile must have identical (or default) input for keyword NMAMethod. Use WRITe to control whether or not the eigenfile is written when not using the READ mode.

The effective RMS coordinate error is needed to judge how the map accuracy falls off with resolution. The extent is needed to determine reasonable rotation steps, and the centre is needed to carry out a proper interpolation of the molecular transform. The extent and the centre are both given in Ångstroms.

SEARCH
- SEARCH ENSEMBLE <MODLID> {OR ENSEMBLE <MODLID>}… NUMBER <NUM>
- The ENSEMBLE to be searched for in a rotation search or an automatic search. When multiple ensembles are given using the OR keyword, the search is performed for each ENSEMBLE in turn. When the keyword is entered multiple times, each SEARCH keyword refers to a new component of the structure. If the component is present multiple times the sub-keyword NUMber can be used (rather than entering the same SEARCH keyword NUMber times).
- SEARCH ORDER AUTO [ON|OFF]
- Search in the "best" order as estimated using estimated rms deviation and completeness of models
- Default: NUM=1
- Default: SEARCH ORDER AUTO ON
SGALTERNATIVE
- SGALTERNATIVE SELECT [ALL|HAND|LIST|NONE]
- Selection of alternative space groups to test in translation functions. ALL tests all possible space groups, HAND tests the given space group and its enantiomorph and LIST tests the space groups listed with TEST <SG>.
- SGALTERNATIVE TEST <SG>
- Alternative space groups to test.
- SGALTERNATIVE SORT [ON|OFF]
- Sort alternative space group list in order of frequency of occurrence
SOLPARAMETERS
- SOLPARAMETERS FSOL <FSOL> BSOL <BSOL>
- Change solvent parameters for Sigma(A) curves. The results are not terribly sensitive to these parameters, which affect only lower resolution data.
- Constraint: 0<FSOL<1, BSOL>0, FSOL<BSOL
- Default: SOLPARAMETERS FSOL 0.95 BSOL 300
SOLUTION
- SOLUTION SET <ANNOTATION>
- Start new set of solutions
- SOLUTION 6DIM ENSEMBLE <MODLID> EULER <A B G> [ORTH|FRAC] <X Y Z> FIXR [ON|OFF] FIXT [ON|OFF] FIXB [ON|OFF] BFAC <BFAC>
- This keyword is repeated for each known position and orientation of a ENSEmble ID. A B G are the Euler angles and X Y Z are the translation elements, expressed either in orthogonal Angstroms (ORTH) or fractions of a cell edge (FRAC). The input ensemble is transformed by a rotation around the origin of the coordinate system, followed by a translation.
- SOLUTION TRIAL ENSEMBLE <MODLID> EULER <A B G> {SCORE <SCORE>}
- Rotation List for translation function
SORT
- SORT [ON|OFF]
- Sort the reflections into resolution order upon reading MTZ file, for performance gain in molecular replacement
- Default: SORT ON
SPACEGROUP
- SPACEGROUP <SG>
- Space group may be altered from the one on the MTZ file to a space group in the same point group. The space group name or number can be given e.g. P 21 21 21 or 19. l.
- Default: Read from MTZ file
SUITE
- SUITE CCP4
- CCP4 style output
- SUITE PHENIX
- Phenix style output
- SUITE CIMR
- CIMR style output
- Default depends on distribution (CCP4 or Phenix)

- Default: TITLE [no title given]
TOPFILES
- TOPFILES <NUM>
- Number of top pdbfiles or mtzfiles to write to output.

- Search volume for brute force translation function. Search region.
- TRANSLATE VOLUME AROUND [ORTH|FRAC] POINT <X Y Z> RANGE <RANGE>
- Search volume for brute force translation function. Search within +/- RANGE Ångstroms (not fractional coordinates, even if the search point is given as fractional coordinates) of a point <X Y Z>.
- Default: TRANSLATE VOLUME FULL
VARSAD
- VARSAD [ {K <N>} | {B <N>} | {SIGMA <N>} | {SA <B1 B2 …>} | {SB <B1 B2 …>} | {SP <B1 B2 …>} | {SD <B1 B2 …>} | {PK <N>} | {PB <N>}]
