Effect on candidate peptide search space. The top pair of curves compares the median number of candidate peptides enumerated for a given peptide length. The bottom pair of curves compares the median number of edges in a spectrum graph for a peptide of a given length. This figure demonstrates the exponential relation between the number of edges in the spectrum graph and the number of candidate peptides.
