Association between a biosample and a gene of interest

If populated, biosample_gene.tsv will contain one row for every biosample linked to an Ensembl gene especially relevant to it. This field is meant to be used for cases such as knockouts, knockins, genetic diseases or other use cases that tie a small number of genes to a biosample. It should not be used to enumerate all genes tied to an object: don't (for example) explicitly link each gene (of thousands) that happens to be expressed in a biosample: the gene associations here should be those that are specific and directly relevant to the study being performed.

All fields are required: this table can be empty (header-row only), but any non-header rows must leave no fields blank.

Some examples:

• If you don't have any biosamples associated with genes, this table should be left empty.
• If you have exactly one gene of interest for each biosample, this table will have the same number of rows as biosample.tsv
• If you have two genes especially relevant to each biosample, this table will have twice as many rows as biosample.tsv

Field	Field Description	Required?	Field Value Type	Extra Info
biosample_id_namespace	Identifier namespace for this biosample	Required	string	This will be the value of id_namespace in the row in biosample.tsv corresponding to the biosample referenced in this row. If your program has not registered multiple CFDE identifier namespaces, this will be exactly the same value for all rows.
biosample_local_id	The ID of this biosample	Required	string	This will be the value of local_id in the row in biosample.tsv corresponding to the biosample referenced in this row.
gene	An Ensembl gene ID	Required	string	This must be a valid Ensembl gene ID Example: ENSG00000010404
