AWS HealthOmics variant stores and annotation stores will no longer be open to new customers starting November 7th, 2025. If you would like to use variant stores or annotation stores, sign up prior to that date. Existing customers can continue to use the service as normal. For more information, see AWS HealthOmics variant store and annotation store availability change.
Default workflow version
After you create one or more versions of a workflow, HealthOmics treats the original workflow as the default version. When you start a run, you can optionally specify a workflow version for the run. If you don't specify a version when you start a run, HealthOmics uses the default version.
In the console, HealthOmics indicates the original workflow with a Default version label. The console uses this label only after you create one or more workflow versions. The original workflow always remains the default version. You can't assign any other version to be the default.
You can't delete a workflow's default version if there are other versions associated with the workflow. For more information, see Delete a private workflow.
