All atoms with their centres outside the box defined by the fractional coordinates
xmin,...,zmax are omitted from the drawing, together with any bonds to them. This is
useful as a 'window' on a packing diagram. The window may be reset by another OMIT
OUTSIDE instruction, or cancelled alltogether by OMIT OUTSIDE 0. Note that
molecules lying across the edge of the window will be drawn incomplete. An alternative
option is the exclusion of all atoms with their centres outside a sphere with radius r
around a specified atom.
Examples: OMIT OUTSIDE C(1) 5 OMIT OUTSIDE 0.5 1 0.5 1 -.25 .25
PACK
This causes a search for all ARU's having their centres inside the box defined by the
fractional coordinates given. By default PACK RANGE displays the contents of a unit
cell. However, this will not show the complete packing arrangement of the crystal; it is
necessary to supply a range that will ensure that a pair of translated molecules will be
found in each axial direction. This is achieved by giving a range of cell translations. In
most structures, the result of a range of two in each axis is usually too congested to be
of any use, so that it is best to restrict the range to one on the axis closest to the view
direction.
Example: PACK RANGE -0.5 1.5 -.5 1.5 0 1
PACK PLAN
ARU's are put in the moles list that satisfy the condition of lying within the range
xmin,...,zmax and in the neighborhood of the specified hkl-plane (d1 and d2 are in
Angstrom).
Example: PACK PLAN 1 1 1 -.5 .5 RANGE -1 2 -1 2 -1 2
