Gene Annotation
File format specification :
| Gene ID | Unique ID |
| Gene Name | Unique name |
| Gene Length | Length of nucleotide sequence |
| Gene Completeness Status | Stating a gene is complete or partial according to the gene predictor |
| Cohort Origin | Stating the cohort contributing the representative gene |
| Taxonomic Annotation(Phylum Level) | Annotated phylum for a gene |
| Taxonomic Annotation(Genus Level) | Annotated genus for a gene |
| KEGG Annotation | Annotated KO(s) for a gene |
| eggNOG Annotation | Annotated eggNOG(s) for a gene |
| Sample Occurence Frequency | Occurrence frequency in samples based on gene profile |
| Individual Occurence Frequency | Occurrence frequency in individuals based on gene profile |
| KEGG Functional Categories | KEGG functional category(ies) of the annotated KO(s) |
| eggNOG Functional Categories | eggNOG functional category(ies) of the annotated eggNOG(s) |
| Cohort Assembled | Stating the metagenomic sequencing cohort(s) contributing the representaive gene or a redundant gene belonging to it |
| #ORFs | % Complete ORFs | Total length (bp) | Average length (bp) | N50 (bp) | N90 (bp) | Max length | Min length | % annotated on Phylum level | % annotated on Genus level | % annotated on KO | % annotated on eggNOG |
| 9,879,896 | 57.74% | 7,436,156,055 | 753 | 1,035 | 384 | 88,230 | 100 | 21.3% | 16.3% | 42.1% | 60.4% |
* ORFs: open reading frame
* N50: it is the length for which the collection of all contigs of that length or longer contains at least half of the total of the lengths of the contigs
* N90: it is the length for which the collection of all contigs of that length or longer contains at least 90% of the total of the lengths of the contigs
* KO: KEGG orthologue group
* eggNOG (evolutionary genealogy of genes: Non-supervised Orthologous Groups)
