Observed versus predicted binding to A*0201 of survivin peptides. HLA-A*0201 binding peptides that bound greater than or equal to 20% of the positive control are listed in column 1 and ranked in column 2. The 17 peptides with iScores are ranked in column 3. Peptides are ranked according to the BIMAS predictions in column 4 (longest predicted half-life = 1). Peptides are ranked according to the SYPEITHI predictions in column 5 (highest score = 1). For all rankings, peptides with the same score are given the same rank. Rank correlations were performed using Excel. *P = 0.05, ** P = 0.01.
