If there is source code for dssr, I am happy to help with implementing such a feature.
Regarding the availability of DSSR source code, please see the thread "Source distribution/Linux packaging" (
http://forum.x3dna.org/rna-structures/source-distributionlinux-packaging/). DSSR 2.0 (to be released) will be formally licensed by Columbia University.
There are open source alternatives to DSSR, including MC-Annotate, RNAView, and FR3D, that may
better suit your needs.
BTW, does the suggested method work? As a general principle, the user who starts a thread is expected to provide a summary, or at least a simple yes/no response. Other viewers of the thread will benefit from your effort. It will also give me more incentive to answer your future DSSR-related questions (if any).
Best regards,
Xiang-Jun
