Hi Ramon,
 Thank you in advance for your help.
 I hope that the dates of stacking base-pair structure are transformed from the cartesian coordinate to PDB format so as to calculating base-pair steps parameter
I don't know how to solve it. Please help me.
Kind regards,
Si-Ya

Hi Xiang-Jun
 I am calculating the structures with QM and thinking to calculate the struc.parameters with 3DNA for some stacking base-pairs.I first use 3DNA and encounter with a trouble on how the cartesian coordinates transform to PDB format.I don't know how to get aroud of this problem. Can you help me?
