    FCS-GX detects contamination from foreign organisms in genome sequences using the genome cross-species aligner (GX). The FCS-GX executable retrieves a Docker or Singularity container and runs a pipeline to align sequences to a large database of NCBI genomes through modified k-mer seeds and assign a most likely taxonomic division.

    FCS-GX classifies sequences as contaminant when their taxonomic assignment is different from the user provided taxonomic identifier. A contamination summary provides an overview of observed contaminant divisions, counts, and total sizes, and an action report provides details and recommended actions for each problematic sequence.
