MetaSim—A Sequencing Simulator for Genomics and Metagenomics
Figure 7
MEGAN visualization of the simHC data set (Sanger technology, read length ≈800 bp).
Arrows point out three of the 11 source genomes of the simulation run that show only few assigned reads at species level compared to the number of originally sampled reads. Due to the fact that C. jejuni subsp. jejuni 81-176, L. lactis subsp. cremoris SK11 and P. aeruginosa PA7 share genes with many closely related strains, most of the sampled reads were assigned by MEGAN to an high-order level in the tree (e.g. genus).
