Hi Gromacs users,<br><br>I am doing the protein lipid system packing step and thus shrinking and minimizing the system alternately but after first minimization rest of all minimization steps show E pot=nan and no minimization step occurs in the em.log file. How to get rid of this problem? Please help.<br>
<br> Yours faithfully,<br>
