Hello,

  I am a new user of gromacs. I am trying to calculate SASA for a protein
system. I have used the command

  gmx sasa -f traj.trr -s md.tpr -o sasa.xvg -n index.ndx

  From this I can only get the total SASA but I want hydrophobic and
hydrophilic SASA separately. I know it can be done using g_sas command for
older version. But I am using newer version of gromacs (gromacs-2016.1).
Please help me to solve this problem. Thanks in advance.
