The genome-analysis pipeline is used to microbial genome annotation. For each sample, this pipeline includes the steps of quality control (KneadData), metagenomic assembly (Spades), gene prediction (Prodigal or MetaGeneMark). The assembly results are run by RNAmmer to predict the location of rRNAs and analyzed by tRNAscan-SE to search for tRNA genes in genomic sequences. Finally, the amino acid sequences of the gene set are aligned (DIAMOND blastp) with the sequences of six common functional databases including EGGNOG (evolutionary genealogy of genes: Non-supervised Orthologous Groups), KEGG (Kyoto Encyclopedia of Genes and Genomes), UniRef90 (The UniProt Reference Clusters 90), CAZY (Carbohydrate-Active enZYmes Database), VFDB (Virulence Factor Database) and CARD (The Comprehensive Antibiotic Resistance Database), thus obtain the functional abundance profile for each sample.
