GROMACS and CPPTRAJ provide a broad range of functionality to users from the Unix command line, or with a simple interactive scripting environment. Based on Python 2 and cython, the MDAnalysis toolkit provides tools for analysis of both protein and membrane properties. Optionally (for now only yet with trjconv) you can write gro files with any number of decimal places, the format will then be n+5 positions with n decimal places (n+1 for velocities) in stead of 8 with 3 (with 4 for velocities).
