Hi all<br><br>I am a new in using Gromacs 4<br><br>I now using g_sas to calculate the solvent accessible surface. Yet, the outcome informs me the Vdw radius is missing for P atom in Vdwradii.dat.<br>Thus I check the file and want to add the value for P. However, though I read through the Manual, I can not find the reference of the source of the values in Vdwradii.dat.<br>
<br>Could some one tell me which paper these radius in Vdwradii.dat come from?<br><br>Thanks<br><br>Huikuan<br>
