<span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; ">I am using Gromacs for Simulation of Insulin.I have generated most of the files but unable to generate the ions.pdb file.The system is becoming idle after the Selection command. A line on the command prompt appears as "replacing solvent molecule with Na" and remains as such for many hours. Is this step really takes too much time or I am doing something wrong. <br>
Thanks</span>
