Yes.

If you are using strict NCS, you can use mtrix-to-ncs-matrix.awk to add
strict NCS matrices (from your MTRIX cards in the pdb file (it uses
add-strict-ncs-matrix). Then use Cell & Symmetry -> Symmetry by
Molecule -> Display Near Chains.

See the "Using Strict NCS" section in the Coot User Manual.
http://www.ysbl.york.ac.uk/~emsley/coot/doc/chapters/user-manual_4.html#SEC70

If you are using non-strict NCS, add-ncs-matrix is what you want.
