<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hello everyone,<br><br> I have been struggling to find a way to supply initial coordinates and initial velocities to a molecule like pentane. I want to add about 2500 molecules of pentane to a box, but all these molecules must have initial positions and velocities. I have used ghemical to draw the molecule and converted it to the pdb format, so I have only coordinates for one molecule. <br> How do I generate initial coordinates and velocities for the other 2499 molecules from scratch? Please, help me out. <br><br>Thank you,<br><br>Lum <br><br><br><br><div><font color="#0000ff"><font face="Times New Roman, Times, Serif"><span class="yshortcuts" id="lw_1221095028_0" style="border-bottom: 1px dashed rgb(0, 102, 204); background: transparent none repeat scroll 0% 0%; -moz-background-clip: -moz-initial;
