</p><p>
I am a new user of gromacs. I am trying to calculate SASA for a protein system. I have used the command</p>
<p>
gmx sasa -f traj.trr -s md.tpr -o sasa.xvg -n index.ndx</p>
<p>
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.<br><br>
