ENA Sequence Retrieval workshop

Warning message

The start date of this training opportunity has already passed

General information

This free course will introduce users to the powerful search and retrieval methods available within ENA (European Nucleotide Archive) for annotated sequences, genomes, raw data and metadata, as well as download options from the ENA browser and an introduction to the various ENA browser tools. There will also be a section on cross references and how to retrieve accessions for other resources linked to the primary data in ENA. There will be time at the end of the course for users to present their own use cases or request specific help for their own queries, enabling them to perform searches to enhance their own research.
