Dear all
Which is the difference between hydropilic and hydrophobic sas?

g_sas computes hydrophobic and hydrophilic surface area based on the absolute value of the partial charge of the atom, which can be adjusted with the -qmax flag.

How can give an interpretation to g_sas xvg graph?

Interpretation of the results is based on the question being asked and the group being analyzed, things that only you know.

What can I find out in it and how can use g_sas to analyze a trajectory?

Start by reading g_sas -h.
