Conformations for nucgen are taken from experimental fibre-diffraction
studies. The basic reference is:

Arnott, S.; Campbell Smith, P.J.; Chandraseharan, R. in Handbook of
Biochemistry and Molecular Biology, 3rd Edition. Nucleic Acids--Volume
II, Fasman, G.P., ed. (Cleveland: CRC Press, 1976), pp. 411-422.

As far as I know, there are no relevant coordinates for left-handed A-DNA.

...good luck...dac
