I think it is something to do with periodic boundary interactions, and I was wondering if there was a way to minimize initial positions. I don't have classical MD parameters ready, as I am running it AIMD, but I can assign GAFF values and run it a round through amber minimization I guess, but I don't know if CP2K can take amber output. Any guidance would be much appreciated. </div><div><br></div><div>With best wishes</div><div>Eric</div><div><br></div><div><br></div><img alt="Screen Shot 2022-05-12 at 10.56.06 AM.png" width="534px" height="368px" src="https://groups.google.com/group/cp2k/attach/5bf4fab969e3a/Screen%20Shot%202022-05-12%20at%2010.56.06%20AM.png?part=0.1&view=1"><br><div><br></div><div><br></div></blockquote></div>
