Table 1 Results of prediction of buried and lipid-exposed faces of TM helices. The columns list the number of helices with correctly predicted lipid-exposed face or lipid-buried face when average lipophilicity (${\overline{L}}_f$), average entropy (${\overline{E}}_f$) or LIPS function (S _f ) was used.
