From: Analysis and comparison of very large metagenomes with fast clustering and functional annotation
Similarity matrices of metagenomes based on families of two COG classes. Matrices are for GOS on COG class F (a), GOS on class T (b), BIOME on F (c), and BIOME on T (d) respectively with significant a factor f = 2 at 0.95 confidence level. Because GOS samples are microbial marine samples, only the microbial (non-viral) water samples from the BIOME data was used. Further, a representative subset from GOS samples was selected so that the figures of GOS and BIOME are similar in size.
