Thanks Justin,

The explanations are very very useful during my course of simulating a
protein with POPC.

I also would like to get explanation on how to simulate a protein which has
only its N-terminal region embedded in the membrane but the rest in solvent.

What is the easy and accurate way to do it?


Position the protein with editconf -center and follow all the other steps in the same way. The dimensions of the box become quite important in such a case. There are some general tips on such placement in another of my tutorials:
