Dear All,

While playing with the exemplary DOPC structure

I've noticed that the bilayer is a little bit asymmetric: where are 65 molecules in one leaflet and 63 in the other.

I'm not sure if this needed to be reported, as it does not appear to have much influence on the properties of the membrane, but perhaps it is important for someone using that model.

Thanks, these bilayers were constructed using self-assembly so they can be slightly asymmetrical. Having a small asymmetry in your bilayer will give you slightly different results, so for proper analysis/results I would advise constructing a symmetrical bilayer; for example using insane (see downloads, proteins and bilayers, tools).

Cheers,
