MD torsions
« on: May 03, 2016, 09:49:50 am »

I am using the last version of 3dna-dssr, 1.5, when I run the analysis on a MD trajectory (option --nrm) I obtain the torsional angle (dssr-torsions.txt) relatively only to the last model of my trajectory)
If I use the --json option, I think to obtain the values for all the torsion angle of each model, but I am not able to manage the file,json
can you help me?

JSON is a standard data exchange format by itself. You need to become familiar with tools such as jq or  underscore etc to parse it. Check my blogposts for some simple use cases.

DSSR does not contains a wrapper for the analysis of MD trajatories (yet). Users are welcome to contribute one, as do_x3dna does for the original 3DNA analysis.
