Thanks you!

Because of the splitting of the lipids on three residues in Lipid14,
should I use it for the following options?

# calculation of apl for popc bilayer composed of 120 lipids
areapermol OL_area :OL,PA,PC nlayers 2 nmols 60 out apm.dat

nmols should be provided for 1 leaflet only?

Thank you!

James
