Well, none of us in this project have the scripting skills necessary for this, that's sort of the problem...

Hi Alex,
I think the best way is to extend the chain, such that you get an overlap between both ends. So for a stretch of DNA
ACGT
You would generate
TACGTA

Then you strip off the terminal atoms and rewire the links over the
boundary. It requires renumbering the topology and at first looks a b

I didn't mean that anything would need to be changed in the description of
residues. The FF handles a
finite chain perfectly.

Yeah, I was trying to avoid that last part. You can tell by now how much I
dislike uhm doing work. :) I'll try it, thanks.
