It is best to keep Gromacs-related questions on the users' list, and I am copying the other members so that an archived copy of this message will be preserved for others to use. Please send questions to the gmx-users list in the future. You also have a much better chance of reaching someone who knows how to solve your problem. See below for my ideas on your situation. > > Range checking error: > />/ Explanation: During neighborsearching, we assign each particle to a grid > />/ based on its coordinates.

It is hard to say what might be the problem, but it appears that mdrun has already told you. What step is this - minimization, equilibration, or production? Did you minimize and/or equilibrate your system, and if yes, then how? What is in your system - a simple protein, or some sort of complex system? Without this information, you will likely get no useful help. Check the gmx-users archive for similar problems. This particular issue has been discussed dozens of times in recent memory. Also consult the wiki site (wiki.gromacs.org), specifically: http://wiki.gromacs.org/index.php/Beginners http://wiki.gromacs.org/index.php/Blowing_Up If you need further help, it will be useful to send the message to the gmx-users list, and include: 1. What your system contains 2. How you have minimized or equilibrated your system 3.
