COVID-19 PubSeq: Public SARS-CoV-2 Sequence Resource

public sequences ready for download!

May 2021 update: we are now at 86,377 sequences with normalized metadata on AWS OpenData!

Edit text!




Here we document the public REST API that comes with PubSeq. The tests run in emacs org-babel. See the bottom of this document for running the tests inside emacs. See bottom of the page how to run tests.

1.1 Introduction

We built a REST API for COVID-19 PubSeq. The API source code can be found in To see if the service is up try

  "service": "PubSeq",
  "version": 0.1

The Python3 version is

import requests
baseURL="http://localhost:5067" # for development
# baseURL=""
response = requests.get(baseURL+"/api/version")
response_body = response.json()
assert response_body["service"] == "PubSeq", "PubSeq API not found"
service : PubSeq version : 0.1

1.2 Search for an entry

When you use the search box on PubSeq it queries the REST end point for information on the search items. For example

collection : fasta : id : MT533203.1 info :

where collection is the raw uploaded data. The hash value in c= is computed on the contents of the Arvados keep collection and effectively acts as a deduplication uuid.

1.3 Fetch metadata

Using above collection link you can fetch the metadata in JSON as it was uploaded originally from the SHeX expression, e.g. using

But better to use the more advanced sample metadata fetcher because is does a bit more in terms of expansion

collection : date : 2020-04-27 fasta : id : MT533203.1 info : mapper : minimap v. 2.17 sequencer : specimen :

1.4 Fetch EBI XML

PubSeq provides an API that is used to export formats that are suitable for uploading data to EBI/ENA from our EXPORT menu. This is documented here.

2 Configure emacs to run tests

Execute a code block with C-c C-c. You may need to set

 '((python . t)))
(setq org-babel-python-command "python3")
(setq org-babel-eval-verbose t)
(setq org-confirm-babel-evaluate nil)

To skip confirmations you may also want to set

(setq org-confirm-babel-evaluate nil)

To see output of the inpreter open then Python buffer.
