Syntax: set unitcell <boolean>
The RasMol unitcell parameter controls the display of the crystallographic unit cell on the current display. The crystal cell is only enabled if the appropriate crystal symmetry information is contained in the PDB data file. The RasMol command show symmetry display details of the crystal's space group and unit cell axes. The set unitcell command is similar the the commands set axes and set boundbox that display orthogonal co-ordinate axes and the bounding box respectively.
