  1. The values of different peptide property used in the study are listed in the table. Values for all the features listed in Table 1 are calculated with these property values during network training. The values for mass, hydrophobicity, helicity and basicity are cited from [19] and the values for PI are cited from http://www.bioscience.org/urllists/aminacid.htm
