Looks up each sample's NCBI BioSample, directly or through an SRA accession (SRR/ERR/DRR run, SRX experiment, or SRS sample), plus the BioProject(s) it belongs to, and stores everything in the project database for viewing in the app and use at export. Lookups are faster with an NCBI API key: the project's `ncbi_api_key` (set in [new_project()]), or else the `NCBI_API_KEY` or `ENTREZ_KEY` environment variable.
Arguments
- path
Path to the project directory (default = current working directory)
- ids
Sample IDs to fetch. Default: every sample with a BioSample value.
- ncbi_ids
Optional BioSample or SRA accessions to set for `ids` first (same length as `ids`). A blank value removes that sample's BioSample and its NCBI data.
- link_sources
Follow links to GEOME, GBIF, or NCBI records named in the fetched records, filling in IDs a sample does not have yet. NULL (default) uses the project setting.
