Dear Tsjerk<br><br>very thanks for your useful guidance.<br><br>I now know that I should compare output of g_gyrate (containing Rg vs time) by area.xvg output file of g_sas (containing area vs time).<br><br>In area.xvg output file, there are several columns: "Hydrophobic", "Hydrophilic" and "Total".<br>
<br>for example in time, 100 ps:<br><br>100 35.9501 60.9389 96.8891<br><br> area is in nm2.<br><br>from above number I understand that 35.9501 nm2 of area of protein that is accessible to solvent belongs to<br>
hydrophobic part of protein.<br><span id="result_box" class="" lang="en"><span title="Click for alternate translations" class="hps"></span></span><br>and 60.9389 nm2 of area of protein that is accessible to solvent belongs to hydrophilic part of protein.<br>
<br>is my understanding true? <br><br>any help will highly appreciated.<br><br><br>
