In this paper, we report our effort on combining both MimoPro and a modified version of Pep-3D-Search together to realize such a collaborative Web tool for supporting users in peptide-epitope mapping. In addition to the process of either MimoPro or Pep-3D-Search alone, the combined operation of Union captures the concept of exploring as many associated peptides as possible from both methods. The concept of mutual verification is realized by the combined operation of Intersection from both methods.
