ENA upload tool

About

The program submits experimental data and respective metadata to the European Nucleotide Archive (ENA). The metadata should be provided in separate tables corresponding to the following ENA objects:

• STUDY
• SAMPLE
• EXPERIMENT
• RUN

The program to perform the following actions:

• add: add an object to the archive
• modify: modify an object in the archive
• cancel: cancel a private object and its dependent objects (under development)
• release: release a private object immediately to the public (under development)

After a successful submission, new tsv tables will be generated with the ENA accession numbers filled in along with a submission receipt.

Tool dependencies

• python 3.5+ including following packages:
  • Genshi
  • lxml
  • pandas
  • requests

  -d, --dev             Flag to use the dev/sandbox endpoint of ENA.
  --vir                 Flag to use the viral sample template.

Mandatory arguments: --action, --center and --secret.

ENA Webin

A Webin can be made here if you don't have one already. The --webin_id parameter makes use of the full username looking like: Webin-XXXXX. Visit Webin online to check on your submissions or dev Webin to check on test submissions.

The .secret.yml file

To avoid exposing your credentials through the terminal history, it is recommended to make use of a .secret.yml file, containing your password and username keywords. An example is given in the root of this directory.

Dev instance

By default the submission will be done using following url to ENA: https://www.ebi.ac.uk/ena/submit/drop-box/submit/?auth=ENA

Use the --dev flag if you want to do a test submission using the tool by the sandbox dev instance of ENA: https://wwwdev.ebi.ac.uk/ena/submit/drop-box/submit/?auth=ENA. A TEST submission will be discarded within 24 hours.

Supported columns for viral sample submissions

Viral samples are validated by ENA using the ENA virus pathogen checklist. The columns supported in the sample tsv table used by this tool are:

Please use the ENA virus pathogen checklist on the website of ENA to know which values are allowed/possible in the restricted text and text choice fields.

The data files

Supported data

• Read data
• Genome Assembly
• Transcriptome Assembly
• Template Sequence
• Other Analyses

Most files uploaded to the ENA FTP server need to be compressed.

More information on how ENA wants to receive the files can be found here.

Tool overview

inputs:

• metadata tables
  • examples in example_table
  • Please define actions in status column e.g. add, modify, cancel, release
  • to perform bulk submission of all objects, the aliases ids in different ENA objects should be in the association where alias ids in experiment object link all objects together
• experimental data
  • examples in example_data

outputs:

• In the same directory of inputs
• metadata tables with updated info in status and other relevant columns, e.g:
  • updated status: added, modified, canceled, released
  • accession ids
  • submission date

Test the tool
