<div dir="ltr">Thanks for the advice; I found the problem. It was a fairly simple mistake, actually; I forgot to include the number of bonds/angles/dihedrals/impropers in the headers of the appropriate sections of the .psf file. I'm not exactly sure how this led to the observed error message, but in any case the problem was indeed with the topology.<div><br></div><div>--Josh</div><div><br>On Friday, March 27, 2015 at 4:06:18 AM UTC-5, Matt W wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;"><div dir="ltr"><div>Hi,</div><div><br></div>I think it comes when the topology of the system is being built, probably for a classical part of the simulation.<div><br></div><div>Two molecules are determined, or defined in a topology file, to be the same type of molecules, but they contain different atom types or similar, so actually are quite different and with different charges.So probably the problem is in your coords/topology.</div><div><br></div><div>Matt</div><div><br><br>On Thursday, March 26, 2015 at 9:19:11 PM UTC, Joshua Carr wrote:<blockquote class="gmail_quote" style="margin:0;margin-left:0.8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I got the following error message after a recent attempt to run CP2K:<div><br></div><div>

I'm not asking anyone to debug my code for me, but can anyone explain to me in a bit more detail what this error message actually means? Generically, what kind of problem does this error message report on, and what are the two integers it outputs? (I've gone through my input files very carefully and can't find any problems, and am trying to narrow down what portions of what files I should be investigating for errors.)</p><p>Thanks,</p><p>Josh</p></div></div></blockquote></div></div></blockquote></div></div>
