Peptide Analyses

Peptide Displacement Fingerprint (PepDF)
Lateral displacement vs Rotational Displacement along the trajectory, for different time windows .

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 and water.
