<div>Thanks for the tip. I didn't think to try it. But if I plan to do any electrostatics I still need the tpr file right? So I would need to produce a top file. Mark, you mentioned making the S-S bonds by hand. </div>

<div>>You still won't get them bonded with this procedure... you need a .top<br>>file with S-S bonds, and you get that by producing one by hand or using<br>>pdb2gmx.</div>
<div> </div>
<div>Could you or anyone else point me in the right direction to do this?</div>
<div> </div>
<div>Again, thanks for all the help and insight.</div>
