Kraken2Tax

Kraken2Tax converts Kraken taxonomic classification output into a Galaxy-compatible taxonomy format for integration into metagenomic analysis workflows.


Key Features:

  • Speed and Efficiency: Leverages Kraken's performance to classify 100 base-pair reads at rates exceeding 4.1 million reads per minute, faster than Megablast and MetaPhlAn.
  • Accuracy: Uses exact k-mer alignment for taxonomic assignment, producing classification accuracy comparable to the fastest BLAST programs.
  • Galaxy Integration: Translates Kraken output into a taxonomy representation compatible with Galaxy to enable downstream analyses.

Scientific Applications:

  • Metagenomic taxonomic profiling: Rapid and accurate taxonomic profiling of metagenomic sequencing data from environmental samples.
  • Environmental and ecological studies: Analysis of environmental samples including studies that collect organic matter via moving vehicles.
  • Comprehensive analysis pipelines: Support for downstream data processing, quality control, statistical analyses, and visualization after conversion to Galaxy-compatible formats.

Methodology:

Applies Kraken's exact k-mer alignment method for taxonomic classification and converts Kraken output into a Galaxy-compatible taxonomy format.
