This is actually pretty challenging to do, but is possible with the right
technique. Have a look at the selection commands in gmx select, which
allows the specification of x,y,z positions. If you know the mid plane of
one leaf in your bilayer, you can specify a molecule type and only take
molecules that have a center of mass within a cutoff of the leaflet mid
plane (which hopefully is on xy plane with fixed z). If you have a large
enough bilayer you may have undulations, which means that you will need to
make a more complicated selection, specifying x, y and z.
