Count records for a species in the European Nucleotide Archive (ENA, EMBL-EBI).

Args: species: Scientific or common name, e.g. "Bos taurus" or "cattle". record_type: "read_run" (sequencing runs), "sample", or "assembly". include_subspecies: Also count subspecies and breeds under this taxon.

Find samples in the European Nucleotide Archive (ENA, EMBL-EBI) for a species.

Optionally filter by country of origin.

Returns the total number of matching samples plus up to limit records with accession, country, collection date, first public date, submitting centre and description.

Args: species: Scientific or common name, e.g. "Bos taurus" or "cattle". country: Country name, e.g. "United Kingdom" or "Kenya". Omit for all countries. limit: Max samples to return (1-100). Default 20. include_subspecies: Also include subspecies and breeds under this taxon.

Get an EMBL-EBI BioSamples record with all its attributes.

Attributes include organism, geographic location, tissue, breed and sex where submitted.

Args: accession: BioSamples accession, e.g. "SAMEA7658521". Use the accession returned by search_samples.

Check whether an ENA/BioSamples sample's metadata is complete and well-formed.

Always checks the fields ENA requires on every sample (organism, collection date, geographic location). Flags fields that are absent, filled with an INSDC missing-value term (e.g. "not collected"), or badly formatted (collection date not ISO 8601).

Args: accession: BioSamples accession, e.g. "SAMEA7658521". extra_fields: Additional attributes to require, e.g. ["sex", "breed", "tissue"] for a livestock (FAANG-style) project.
