Bio3d Analysis
Bio3d is an R package for doing all kinds of structural manipulations and computations.
It seems to not allow one to parse trajectories frame-by-frame making analysis of large trajectories very difficult. Fortunately, the R code to parse dcd files is simple enough that I developed a function to iterate over the frame, rather than loading the trajectory into memory.
