Diagram of peptides found in multiple datasets. All overlaps of peptides are shown (two way, three way, and four way) for all four input datasets: in-gel 1 (green), in-gel 2 (yellow), in-solution 1 (blue), and in-solution 2 (red). Numbers represent the number of shared peptides in the respective overlapping areas.
