In addition to a variety of management commands available via the Heroku CLI, Heroku Postgres provides a web dashboard, the ability to share queries with dataclips, and several other helpful features. You can access a Heroku Postgres database from any language with a PostgreSQL driver, including all languages officially supported by Heroku. Heroku Postgres is a managed SQL database service provided directly by Heroku. Eligible students can apply for platform credits through our new Heroku for GitHub Students program. If you have apps using any of these resources, you must upgrade to paid plans by this date to ensure your apps continue to run and retain your data. The public Postgres database allows anyone to run the RNAcentral website locallyĪnd contribute new code to RNAcentral using the instructions available on GitHub.Starting November 28, 2022, free Heroku Dynos, free Heroku Postgres, and free Heroku Data for Redis® plans will no longer be available. Requires psycopg2 to connect to Postgres: pip install psycopg2 The file output.fasta will contain the desired subset of RNAcentral sequences in FASTA format. The command will create a file ids.txt with a list of RNAcentral identifiers.ĭownload the following RNAcentral FASTA file:Įxtract the sequences using seqkit: seqkit grep -f ids.txt rnacentral_species_specific_ > output.fasta Run the following command to execute the query: docker run -v `pwd`:/rnacentral -it postgres /bin/sh -c 'cd /rnacentral & psql -t -A -f query.sql > ids.txt' Tax.lineage LIKE 'cellular organisms Bacteria %'ĪND precomputed.is_active = true - exclude sequences without active cross-references If you need to export more sequences, you can use the following workflow: The RNAcentral text search can only export up to 1,000,000 search results. You can still query RNAcentral using VEGA identifiers: SELECT Identifiers are no longer searchable using the RNAcentral text search, rnc_rna_precomputed - contains RNA types and descriptions for all sequencesĮxample queries Search by external accessionsĪlthough the VEGA database has been archived and its.rnc_accessions - contains metadata associated with each cross-reference. rnc_database - contains a list of Expert Databases.xref - contains cross-references to Expert Databases.rna - contains RNA sequences and URS identifiers.The entire RNAcentral schema contains more than 40 tables, but the following tablesĪre good starting points for exploring the data: The following diagram was generated based on RNAcentral release 20. If your computer is behind a firewall, please ensure that outgoing TCP/IP connections to the corresponding ports are allowed. Psql tip: if you don't have psql installed on your machine, consider using Docker to get started with a pre-configured Postgres image:ĭocker run -it postgres psql you can use a Postgres client like DBeaver or PgAdmin. To connect to the database using command line: The database is updated with every RNAcentral releaseĪnd contains a copy of the data available through the RNAcentral website. In addition to downloadable files, an API,Īnd the text search, RNAcentral provides a public
