WebCPPTRAJ has the notion of "data sets" which can be of multiple formats. Here we create a coordinate dataset that will save all of the input frames. This allows us to act on the entire set later without have to re-read in the trajectories from disk. We refer to the loaded frame coordinate dataset as: cpu-gpu-trajectories . WebCPPTRAJ supports a variety of clustering algorithms, distance metrics, clustering metrics, and output options. This example will use trajectories of the tetranucleotide rGACC that were generated using multidimensional replica exchange (MREMD, 24 x Temperature, 8 x aMD).
