Abundance profiling of samples originating from spatially distant locations using a taxonomically and functionally annotated reference gene catalog provides the framework for answering the simple, yet central question quantitative metegenomics attempts to address: "Who is doing what and where?". We assembled billions of DNA shotgun sequencing reads to reconstruct microbial community genomes. Genes were predicted on these "contigs" and together with genes from publicly available genomic and metagenomic data sets (see box on sidebar) they were clustered to generate a non-redundant set of reference genes. Public data sets include:
| Data sources of the OM-RGC | |
|---|---|
| Source | Genes |
| Tara | 111,530,851 |
| Global Ocean Sampling | 22,607,701 |
| Pacific Ocean Virome | 1,777,775 |
| Moore Phage Viral Genomes | 14,790 |
| NCBI reference genomes | 1,592,583 |
| Redundant genes | 137,523,700 |
| OM-RGC (filtered, non-redundant) | 40,154,822 |

For each prokatyote-enriched sample (N=139), we extracted metagenomic merged Illumina reads (miTAGs) that contained signatures of the 16S rRNA gene (Logares et al. 2013):
16SrRNA miTAG sequences [ Size: 509 MB | MD5 sum: 0f56e3caef6cfd501013db9c9b7d4e6f ]These fragments were mapped to a set of 16S reference sequences that were downloaded from the SILVA database (Release 115: Quast et al. 2013) and clustered into 97% operational taxonomic units. The OTU count table was summarized at different taxonomic levels and can be downloaded here:

After generating the reference gene catalog, reads from each sample were mapped to the catalog to estimate functional and taxonomical abundances.For each prokaryote-enriched sample (N=139), the abundance of each gene in the OM-RGC was determined using MOCAT (Kultima et al. 2012). Based on the functional annotations of the OM-RGC, these gene abundances were summarized at the level of: (i) eggNOG gene families (genes annoted to the eggNOG version 3 database: Powell et al. 2011), (ii) KEGG orthologous groups and (iii) KEGG modules. We provide profiles based on the full catalog and based on the subset of genes that were annotated as bacterial or archaeal.

Raw paired-end Illumina reads were trimmed form the 3’ and 5’ ends, and reads shorter than 45 bp were removed. To minimize artificial contamination, high quality reads matching any adapter sequence used in the sequencing step, were discarded. After removal of reads matching adapter sequences, the reads were assembled into scaftigs (contigs that were extended and linked using the paired-end information of sequencing reads). Only scaftigs longer than 500 bp were kept. After assembly, gene-coding sequences were predicted on the assembled scaftigs. The data can be downloaded from the EBI-ENA:
