ncbitaxonomy

ncbitaxonomy

This is a Rust crate (i.e. library) for working with a local copy of the NCBI Taxonomy database. The database can be downloaded (either taxdump.zip or taxdump.tar.gz) from the NCBI Taxonomy FTP site and reformatted into a SQLite database using the taxonomy_util utility's to_sqlite subcommand.

Documentation is available at crates.io.

taxonomy_filter_refseq

(new in 0.1.1)

A tool to filter a NCBI RefSeq FASTA file so that only the ancestors of a given taxon are retained.

$ taxonomy_filter_refseq --help
taxonomy_filter_refseq 1.0.0
Peter van Heusden <pvh@sanbi.axc.za>
Filter NCBI RefSeq FASTA files by taxonomic lineage

USAGE:
    taxonomy_filter_refseq [FLAGS] [OPTIONS] <INPUT_FASTA> <ANCESTOR_NAME> [OUTPUT_FASTA]

FLAGS:
        --no_curated      Don't accept curated RNAs and proteins (NM_, NR_ and NP_ accessions)

OPTIONS:
    -d, --db <TAXDB_URL>    URL for SQLite taxonomy database

ARGS:
    <INPUT_FASTA>      FASTA file with RefSeq sequences
    <ANCESTOR_NAME>    Name of ancestor to use as ancestor filter
    <OUTPUT_FASTA>     Output FASTA filename (or stdout if omitted)

taxonomy_filter_fastq

(new in version 0.2.0)

$ taxonomy_filter_fastq --help
taxonomy_filter_fastq 1.0.0
Peter van Heusden <pvh@sanbi.axc.za>
Filter FASTQ files whose reads have been classified by Centrifuge or Kraken2, only retaining reads in taxa descending
from given ancestor

OPTIONS:
    -A, --ancestor_taxid <ANCESTOR_ID>                      Name of ancestor to use as ancestor filter
    -d, --db <TAXDB_URL>                                    URL for SQLite taxonomy database
    -F, --tax_report_filename <TAXONOMY_REPORT_FILENAME>    Output from Kraken2 (default) or Centrifuge

ARGS:
    <INPUT_FASTQ>...    FASTA file with RefSeq sequences

taxonomy_util
