Chemfiles is a modern and high-quality library for reading and writing trajectory files created by computational chemistry simulations program. These trajectories contains atomic positions, velocities, names, topology and sometimes more. Running simulations produce enormous amounts of data, which has to be post-processed to extract physical information about the simulated system. Chemfiles provides an interface to access this information which is - unified: the same code will work with all the supported formats; - simple: the interface is easy to use and extensively documented. ...

...The approach is general and the definition of PIV only requires to specify the range of interatomic distances that is relevant for the process under study. Alternatively, also the SPRINT topological coordinates can be employed, that are particularly suited for nanostructures. The output is a partitioning of the trajectory into a few structural clusters (i.e., sets of frames), allowing for simpler analysis and visualization. Please read and cite Gallet & Pietrucci, J.

md-utils is a set of command line tools written in C designed to perform certain operations and analysis on the molecular dynamics data. The supported operations involve trajectory coordinate transformation to the COM system, Cartesian coordinate transformation to selected internal coordinates and to projected normal mode coordinates, trajectory merging, selecting subsets of trajectory frames, selecting subsets of atoms, permuting atoms, etc. Analysis tools involve 1D, 2D and 3D data binning (histograms), volumetric data handling, etc. ...
