[phenixbb] sugar puckering in an ideal B-DNA

[Miguel Ortiz-Lombardía]

Well, in fact, B-DNA built with coot is slighlty C2*-endo and markedly
C3*-exo. In comparison a B-DNA built with X3DNA is markedly C2*-endo. See
the attached figures. I agree with Maia that this is what I would have
expected. Perhaps Paul can tell us where does coot take the "ideal" values
from?

Cheers,


Miguel
