Welcome to pATLAS, the plasmid atlas.


pATLAS is a web-base tool that empowers researchers to easily and rapidly access information related with plasmids present in NCBI's refseq database. In pATLAS each node (or circle) represents a plasmid and each link between two plasmids means that those two plasmids share over 90% average nucleotide identity.

With this tool we have two main goals:

  1. Increase the accessibility of plasmid relevant metadata to users as

    well as facilitate the access to that metadata.

  2. Improve the ease of interpreting results from High Throughput Sequencing

    (HTS) for plasmid detection.

Main features

  • Browse by taxa.

  • Browse by resistance genes.

  • Browse by plasmid families.

  • Browse by virulence genes.

  • Import JSON files from mapping results, mash screen results and mash

    dist results (for assemblies).

  • Generate many plots for custom selections.

  • Download sequences for selected plasmids.

  • Display metadata for one plasmid or multiple selected plasmids.

  • Ability to share projects between sessions and users.
