Red solid plot : values according to the hydrophobicity scale of Kyte and Doolittle (reference paper).


Yellow dashed plot : Experimentally determined hydrophobicity scale for proteins at membrane interfaces(reference paper).


Green dotted-dashed plot : prediction of transmembrane helices (reference paper). In this scale (unlike the others), more negative values reflect greater hydrophobicity.
