search direct {<xray-search-direct-statement>} end
<xray-search-direct-statement> :==
nlist=<integer>
Specifies the number of highest peaks of the rotation function that
will be listed.
epsilon=<real>
Epsilon for cluster analysis. This defines a matrix norm to
determine whether two rotation matrices are close. The default
value is reasonable for 10 degree grids.
symbol=<string>
Root name for the symbol table. If blank to table is created (this is
the default.
symmetry=?|reset|<symmetry-operator>
Define symmetry operators which are required for proper grouping of
symmetry related peaks during cluster analysis.
?
Prints current parameters and options.
The following symbols are created upon completion:
$<symbolname>_nlist - number of peaks
$<symbolname>_rfvalue_<i> - rotation function value
$<symbolname>_theta1_<i> - for Eulerian and Lattman mode
$<symbolname>_theta2_<i> - for Eulerian and Lattman mode
$<symbolname>_theta3_<i> - for Eulerian and Lattman mode
$<symbolname>_phi_<i> - for spherical polar angle mode
$<symbolname>_psi_<i> - for spherical polar angle mode
$<symbolname>_kappa_<i> - for spherical polar angle mode
where <i> runs through the clustered peak list.
The target for the direct rotation search is the current xray target
which must be defined.
