Description

Assembly

Genome length, average genome length, N50, GC content and sequencing depth

  • Genome length – an estimate of the draft genome assembly length

  • Average genome length – average read length of genomes

  • N50 – length of smallest contig covering 50 % of genome

  • GC content – guanine–cytosine content of draft genome

  • Depth – no. of times each nucleotide position in the draft genome has a read that aligns to that position

Phylogeny

  • SNPs are used to infer phylogenetic relationships between samples

Variant calling

SNPs

  • SNP – a single-nucleotide base change from the reference genome that occurs anywhere within the genome

Antimicrobial resistance profiling

Contig, gene, identity, product

  • Contig – continuous consensus nucleotide sequences without gaps

  • Gene – antibiotic resistance gene identified within the assembly

  • Identity – percentage representing exact nucleotide matches

  • Product – artefact produced from antibiotic resistance gene

Pangenome analysis

Core genes, soft core genes, shell genes, cloud genes

  • The genes are compared against each other across samples to predict genome plasticity and to detect how much of the accessory genome has been taken up by organisms over the course of time
