Friends,<br>I guess when i select no. of water as &quot;sel ::WAT &amp; protein z&lt;3&quot;, i the distance of water is chosen as distance from atom protein atom centres. Instead i want to calculate no. of water around the protein Vdw surface with same distance value. Any idea would be of great help. <br>
<br>Thanks,<br>Bala<br clear="all"><br>
