 | `SAMPLE_NAME/SAMPLE_NAME.pergene.tsv` | Taxonomic affiliation of genes. One line corresponds to a gene (1st column), its corresponding taxon id (2nd column), its corresponding lineage (3rd column) and the tax ids of each level of this lineage (4th column). |
 | `SAMPLE_NAME/SAMPLE_NAME.warn.tsv` | List of genes with a hit without corresponding taxonomic affiliation. Each line corresponds to a gene (1st column), the reason why the gene is in this list (2nd column) and match ids into the database used during `05_alignment/05_2_database_alignment/` (3rd column). |
+| `SAMPLE_NAME/top_taxons_per_contig.tsv` | Possible affiliation taxons at each rank and for each contig (one line per contig). The score associated with the taxon is indicated in parenthesis. This file can be helpful to investigate contig affiliation. |
 | `SAMPLE_NAME/SAMPLE_NAME.percontig.tsv` | Taxonomic affiliation of contigs. One line corresponds to a contig (1st column), its corresponding taxon id (2nd column), its corresponding lineage (3rd column) and the tax ids of each level of this lineage (4th column). |
 | `SAMPLE_NAME/SAMPLE_NAME_quantif_percontig.tsv` | Quantification table of reads aligned on contigs affiliated to each lineage of the first column. One line = one taxonomic affiliation (1st column, `lineage_by_level`), the corresponding taxon id (2nd column, `consensus_tax_id`), the tax ids of each level of this taxonomic affiliation (3rd column, `tax_id_by_level`), the name of contigs affiliated to this lineage (4th column, `name_contigs`), the number of contigs affiliated to this lineage (5th column, `nb_contigs`), the sum of the number of reads aligned to these contigs (6th column, `nb_reads`) and the mean depth of these contigs (6th column, `depth`). |
 | `SAMPLE_NAME/SAMPLE_NAME_quantif_percontig_by_[taxonomic_level].tsv` | One file by taxonomic level (superkingdom, phylum, order, class, family, genus, species) for the sample `SAMPLE_NAME`. Quantification table of reads aligned on contigs affiliated to each lineage of the corresponding [taxonomic level]. One line = one taxonomic affiliation at this [taxonomic level] with is taxon id (1st column, `tax_id_by_level`), its lineage (2nd column, `lineage_by_level`), the name of contigs affiliated to this lineage (3rd column, `name_contigs`), the number of contigs affiliated to this lineage (4th column, `nb_contigs`), the sum of the number of reads aligned to these contigs (5th column, `nb_reads`) and the mean depth of these contigs (6th column, `depth`). |
