Dear all,
I'd like to use chimera to do a picture of a circular DNA with ribbon 

I found the two following problems:
1.If I load the .pdb files, chimera is unable to recognize the topology 
and shows extra-bond connecting the last base of a strand with the 
previous of the other strand.
2.If I load the AMBER topology, the connectivity is correctly 
recognized, but the first base and last are not connected by  the ribbon.

Is there any solution?
