Hi Xiang-Jun,

I am not sure since I havent' checked 3DNA pages for a while
if you implemented a feature to detect Z-steps in RNA and DNA systems
as defined in:
(if not, I think it would be nice to have and probably pretty easy to do for you).

Thanks for your reply,

All the best,

Hi Pascal,

I read both of your papers mentioned above, and like the thoroughness of your analyses. 3DNA/DSSR certainly contains features for characterizating Z-steps in DNA/RNA, and I could consolidate them into a more user-friendly form.

For the benefit of other users, and to avoid any potential technical caveats, please provide concrete examples with defining features of Z-steps, presumably based on your publications.

Best regards,
