Dear All,
I see in MD simulations, the number of lipids is 128 or multiples of 128.
Can someone tell me why ?
Probably convenience (easy to create 8 x 8 grid for each layer) and adequate
sampling.
Whether can i choose another number of lipids ?
Sure, if you can produce a suitable configuration and gather sufficient data.
Carving out a subset of lipids from an existing bilayer is hard because you
probably won't get a regular shape, but you can create your own bilayers if you
like. If you want more lipids, you can multiply any existing bilayer simply by
using genconf -nbox.
