Normalized metadata for the Sequence Read Archive

MetaSRA is an annotation/re-coding of sample-specific metadata in the Sequence Read Archive using biomedical ontologies. Currently, MetaSRA labels biological samples with terms in the Disease Ontology, Experimental Factor Ontology, Cell Ontology, Uberon, and Cellosaurus.

Search the MetaSRA

The Ontology Lookup Service and Cellosaurus can be used to find a specific ontology term of interest within the ontologies. The MetaSRA can be queried for an ontology term using the form below:


(Enter the name or synonym of the ontology term of interest. You can also enter an ontology term ID.)

Filter by sample-type (select 'All' to avoid filtering):

Cell line
Primary cells
In vitro differentiated cells
Stem cells
Induced pluripotent stem cells
