Retrieve

Query the MetaHQ database to retrieve sample or study annotations for tissues, diseases, sex, and age.

metahq retrieve diseases --terms "MONDO:0004994,MONDO:0008903" \
--level sample --filters "species=human,tech=rnaseq,ecode=expert" \
--metadata "sample,series,platform,srp" --fmt parquet

Search

If you do not have ontology terms memorized off-hand, shame on you. However, you can cheat and run the following command to find the ontology term IDs most similar to a free-text query of a disease, tissue, or cell line.

metahq search --query "heart attack" --type disease --ontology MONDO
