Import your known variants
To make an import into the Biomedical Genomics Workbench, you should have your variants in GVF format (http://www.sequenceontology.org/resources/gvf.html or VCF format http://ga4gh.org/#/fileformats-team).
Please use the Tracks import as part of the Import tool in the toolbar to import your file into the Biomedical Genomics Workbench.
