Hi Users,<br> I want to calculate lateral diffusion coefficent of popc bilayer by using g_msd , the information I understood from one journal (<a href="http://dx.doi.org/10.1063/1.2393240">http://dx.doi.org/10.1063/1.2393240</a>) is that P atom select and feed to g_msd command . I have to take only single P atom or all Patoms of POPC biliayer ? and how can i select by using make_ndx? Could you please tell me<br>
Thanks in advance.<br>
