15 | biobb_analysis CpptrajImage
16 | Wrapper of the Ambertools Cpptraj module for correcting periodicity (image) from a given cpptraj trajectory file.
17 | Cpptraj (the successor to ptraj) is the main program in Ambertools for processing coordinate trajectories and data files. The parameter names and defaults are the same as the ones in the official `Cpptraj manual <https://amber-md.github.io/cpptraj/CPPTRAJ.xhtml>`_.
