search_sequence

Similarity search by raw RNA sequence. Submits the sequence to the RNAcentral sequence-search service, polls for completion, and returns the top hits across the member databases.

Use this when you have a nucleotide sequence and want to know what it matches in RNAcentral. If you already have an accession or a name, use query_rnacentral.

Arguments

Name

Type

Required

Description

sequence

str

yes

The RNA (or DNA) sequence to search. Case-insensitive; whitespace is ignored.

databases

list[str]

no

Restrict the search to specific member databases. Defaults to all.

Returns

A markdown summary of the hits: accession, description, organism, E-value/identity, and the source database.

Notes

  • The upstream service is asynchronous — the tool submits a job and polls until results are ready or a timeout is hit. Expect a few seconds of latency on a cold cache.

  • Very long sequences or highly repetitive sequences may be rejected by the upstream service; the tool surfaces the error message verbatim.
