Project Summary
This community project extends the current i2b2 query functionality by providing the ability to query for genotyped subjects by specific annotations related to genetic variants. Also, new query widgets have been built in the i2b2 web client that leverages existing i2b2 infrastructure for querying large strings of text stored in the observation_blob field of the observation_fact table.
...
- Source code for ETL process of VCF files
- Example i2b2 ontology & metadata XML
- Example data representation & SQL scripts
- Web Client widgets to submit queries
