<br>Hi everyone, I have a question regarding a forcefield build.<br>Is there a way to specify in the topology file how to bond two molecules<br> one to another?<br><br>So this thing, a halfaring + carboxyl on the left is one molecule and similar<br>
thing on the right is the other molecule. But I need to bond carbons a and b<br> to get the full ring. Is this possible? Please don't ask me why I didn't make the <br>whole thing one molecule (it is convinient for some other reason) I am using my<br>
own bonds angles and dihedrals, not "virtual sites" or any of that stuff. <br>Is that "+" and "-" stuff from rtp file going to work here? Thanks, Frankie<br> H H<br>
