Accessing the Downloads

All metadata and results from calculations done by Pathogenwatch are available to download in various formats. Most downloads can either be accessed by selecting genomes in the Genome Browser view and clicking on the "Selected Genomes" button in the top right corner and then "Downloads" or via the "Downloads" button in the Collection View. Additionally, assembly FASTA files and GFF files can be obtained by clicking the icons in the Metadata Tables in the leftmost column.

Downloads can take some time to generate for large collections.

Available Downloads

The downloaded FASTA files are compressed using zip. Generally you'll need to unzip the bundle before using the files in other software.

FASTA Files

The original uploaded FASTA files for each assembly. The FASTA downloads can be accessed from the Selected Genomes popup and from the Metadata tables in the Collection.

GFF Files

A GFF format output of the core, MLST, and AMR results is available for each assembly from the Metadata Tables in the Collection View.

  • The score ({s}) is the percent identity to the reference allele.

  • The Name attribute is the Pathogenwatch gene family name.

  • Target is the reference allele identifier and the start-end of the match.

  • The score ({s}) is the percent identity to the reference allele.

  • The Name attribute is the Pathogenwatch gene family name.

  • Target is the reference allele identifier and the start-end of the match.

  • "_PAAR" are presence/absence matches.

  • "_SNPAR" are for gene variants.

Notes on "_SNPAR"

  • Consists of two components - (1) the match to the SNPAR genes (type=CDS) (2) the individual resistance mutations (type=point_mutation)

  • The CDS record describes the reference gene and match statistics. There can be 1 or more mutation records that cause an amino acid change leading to resistance. Each mutation should have a reference to a parent CDS feature.

Apart from the FASTA and GFF files, the rest of the downloads are plain text CSV for easy use with other software

AMR

AMR Profile

The overall AMR profile - i.e. the antibiotics for which potential resistance genotypes have been identified for each assembly - is available from the Selected Genomes popup and the Collection View Downloads. The header consists of genome name, id, analysis module version and each antibiotic for that species. Possible values are "NOT_FOUND", "INTERMEDIATE" and "RESISTANT"

Core Allele Distribution

The presence/absence table of Pathogenwatch scheme core matches is available from the Collection View downloads. Family names are given in the column header with one row per assembly. The percentage overlap with the reference is given as a value between 0-1 ("0" is absent, "1" is complete and present. Multiple hits to the same family are separated with semi-colons.

Score Matrix

The final score matrix used to build the neighbour-joining collection trees are available from the Collection View downloads. The score is the number of differences normalised by the percentage of the core matched, and so is typically almost identical to the number of differences.

Difference Matrix

The number of counted differences between each pair of assemblies in the current selection can be downloaded from the Collection View. For more details on how this is calculated see the Core Genome Tree section.

Variance Summary

A summary of variance seen in the selected genomes, also sub-grouped by nearest reference, can be downloaded. An example of the output is given below.
