Distribution of clusters and reads by KOG functional class and library. Distributions of clusters over KOG class for clusters shared between the 1N and 2N libraries and clusters unique to each library. Fisher's exact test was used to determine significant differences in the distribution of clusters by KOG class between the 1N-unique and 2N-unique sets (asterisks indicate the KOG classes exhibiting significant differences between the 1N-unique and 2N-unique sets); P < 0.002 without correction for multiple tests). The same test was applied to determine differences in the distribution of clusters by KOG class between the set of shared clusters and both 1N-unique and 2N-unique clusters (the at symbol (@) indicates KOG classes exhibiting significant differences between the 1N-unique and shared sets; P < 0.002 without correction for multiple tests).
