PLoS One particular 2012, 7:e31386.Making use of the GAIIx evolved mock metagenome, we determined the effect of metagenome size on estimated community viral diversity. We created subsets of this metagenome containing 24,658, 248,525 and two,485,933 reads. Their contig spectra was calculated with Circonspect [1] working with the Minimo assembler [35] title= dar.12119 employing all reads and default parameters (98 identity, 35 bp overlap). Then, both PHACCS and CatchAll were employed with their default values to fit the contig spectra utilizing all accessible models. Utilizing the hundred 454 mock metagenomes, we calculated the accuracy of viral diversity estimates obtained working with PHACCS, CatchAll and UCLUST as a function of neighborhood structure.Ndance and have been classified in four community structures, varying in richness (100 or 1,000 species) and evenness (most abundant genome at two.0 or 25 relative abundance). We let Grinder automatically randomly create 25 metagenomes of every single sort (total of 100 metagenomes) for statistical replication.Estimation of viral diversityCompeting interests The authors declare that they have no competing interests. Author contributions DAC and AA conceived the study. DAC carried-out the analyses, with the exception on the hundred mock communities generation and their diversity evaluation contributed by FA. DAC wrote the manuscript with input in the co-authors. All authors read and approved the final manuscript. title= fnins.2013.00232 Acknowledgments We thank the Genomics unit Antonia Mart Gallardo at Parque Cient ico de Madrid for providing the necessary sequencing runs to construct the error models.
