Heat maps of relative position-specific amino acid propensities (P x ). Px values of amino acids were computed for EL-Manzalawy analysis and control subsets (left, top and bottom respectively) and Chen analysis and control subsets (right, top and bottom respectively). Px values were computed as the ratio of the frequency of occurrence of the amino acid in the epitopes pool over the frequency of occurrence of the same amino acid in the non-epitopes pool at a specific position. Px values were calculated using the epitopes and non-epitope pools in the analysis subsets, and using the two pools of non-epitopes in the control subsets. Increasing color intensities in the red spectrum indicate enrichment in epitopes pool (high Px) while increasing color intensities in the blue spectrum indicate enrichment in non-epitopes pool (low Px).
