Peptide Analyses
Peptide Displacement Fingerprint
(PepDF)
Lateral displacement vs
Rotational
Displacement along the trajectory, for different time
windows .
Tilt angle: 
Peptide tilt angle evolution, defined as the angle between the peptide helical axis and the bilayer normal .
Peptide spin: 
Evolution of the angle formed by the transversal component of the hydrophobic dipolar moment and a vector transversal to the peptide pointing outwards the membrane.
Lipid Analyses:
Area per lipid
In this system both leaflets have the same number of lipids, thus the values for their APL are overlaping in the plot
Density maps:
2D-density maps of lipids around the
peptide
along XY and YZ axis, calculated for each lipid type along the
last
microsecond.
Lipid-Peptide Analyses:
z-Position
Z-coordinate, averaged for
differetn
parts of the the system: peptide, membrane, first and
last
backbone (BB) residues and upper of lower leaflet
lipids’
headgroups (HGs).
Minimum distance
Minimum distance (nm) between the
peptide backbone and the lipids (headgroups and
tailgroups).
Number of contacts
Number of contacts between the
peptide backbone and the water or the lipids separated
by
lipid headgroups (HG) or lipid tails, using a cut-off of
0.6
nm.
Lateral density
Lateral density for the different
components of the system: headgroups, tail groups,
peptide
