Functional and Taxonomic Profiling of MAGs

These tools allow users to examine the genetic potential of a community and investigate the strain frequencies of subpopulations in those communities.

Apps

• Meta-Decoder Call Variants: Identify polymorphisms within microbiome read sequences against reference genomes.

  • Map Reads to Reference Sequence: Map reads to a reference genome.

  • Call Microbial SNPs: identify single nucleotide polymorphism (SNP) variants based on mapped reads.

• StrainFinder v1: Determine strain genome sequences from sub-populations of allele frequency.

  • strainFinder Repository

• FamaProfiling: Generate a functional profile of nitrogen cycle genes or universal single-copy markers for metagenomic read libraries and assembled genomes.

  • Fama Read Profiling

  • Fama Genome Profiling

Inputs

These apps take metagenome-assembled genomes (MAGs) as Genome objects input. See Metagenomic and Community Analysis for an overview of metagenomic workflows.

Narratives

• Groundwater MAGs from Tian et al., 2020 – provides an example of the workflow using MAGs
