Is your feature request related to a problem?
gmx do_dssp isn't making nice with DSSP version 3.1.4, and I would like to quantify the secondary structure of my protein.
Describe the solution you'd like
An MDAnalysis version where I don't need to load my entire trajectory into memory.
Describe alternatives you've considered
MDTraj has compute_dssp but it loads the trajectory into memory.
