Given the reactivity of an antibody repertoire for random peptides, what were the original antigens which the antibody repertoire bound to.

Lu's ideas for the decipher problem
-He points out that the peptides with the true epitopes are often not in the lists with the best p-value obtained from normal vs disease. However, the peptides with the true epitopes are obtained when you look at normal vs many other diseases or a disease vs many other diseases.

some of my notes about how decipher can be performed. . . or at least how the decipher space can be better defined (for pre 07-01-2014d1303)

Choose peptides from 330K with t-test -> find epitopes ((Method 1 Script of Josh based on occurrence of exact match in sublibrary vs match in library) (Method 2 Use glam2 with selection of all possible 5 peptides to reduce noise)) -> Search database with epitopes ((Method 1 BLAST) (Method 2 MAST)) -> Validate findings by repeating procedure with random peptides and random life space peptides
