Title: where are the torsion angles?
Post by: annawacker on May 28, 2026, 10:10:02 am

I am missing the torsion angle analysis on the new web3DNA server. why is it gone?

Hi,

Thank you for your question. DSSR calculates a wide range of structural features, including backbone torsion angles. To keep the initial release of the wDSSR web server streamlined and accessible, some of these detailed parameters were intentionally omitted from the default display. In the meantime, you can obtain complete torsion angle profiles using the DSSR command-line tool, as detailed in the DSSR User Manual (http://docs.x3dna.org/dssr-manual.pdf).

We can update wDSSR to make this data available on the web interface. Would you prefer to have the torsion angles included in a downloadable JSON output file, or displayed explicitly in a new section on the results page?

Best regards,

Xiang-Jun
