Hi Linda,
  The six clipping planes are user-defined. You can set the
center point and a normal for each clipping plane independently
using the "mol clipplane" commands:
  mol clipplane center <clipid> <repid> <molid> [<vector>]
  mol clipplane normal <clipid> <repid> <molid> [<vector>]
  mol clipplane color <clipid> <repid> <molid> [<vector>]
  mol clipplane status <clipid> <repid> <molid> [<mode>]
  mol clipplane num

If you'd prefer an easier tool to manipulate the clipping planes
and aren't necessarily attempting to apply them to just one
representation, we have a plugin for this purpose in the menu
  Extensions->Visualization->Clipping Plane Tool
