15 | biobb_analysis CpptrajSlice 

16 | Wrapper of the Ambertools Cpptraj module for extracting a particular trajectory slice from a given cpptraj compatible trajectory. 

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>`_.
