Distribution of PeptideAtlas peptides on the human genome. Each chromosome is described by three columns. The left-most column shows a chromosome's standard banding. The right-most column presents a histogram of the mapping of peptides to chromosomal regions; a line's length represents the number of peptides mapped to a chromosomal region. The central column indicates the over/under representation of peptides in a given region. Green regions represent more mapped peptides than expected at uniform random; red regions indicate fewer mapped peptides than expected at uniform random.
