[gmx-users] g_sas

[Gonzalez Fernandez, Cristina]

Dear Gromacs users,





I want to calculate the hydrophobic and hydrophilic area of a protein by using the g_sas command. I have used:

g_sas -f md.xtc -s md.tpr -o area.xvg -tv volume.xvg



However, looking at the area.xvg with xmgrace, I can only see the hydrophobic area not the hydrophilic. Besides, looking at the volume.xvg I can only see the volume, not the density. Could anyone help me to see both hydrophobic and hydrophilic area of my protein as well as its volume and density?





Any help will highly been appreciated.



Best,

C.
