Opal 4.14 Release Notes

Jeanette McCarthy -

29 October 2015

We are excited to announce that Opal 4.14 is live! In this release, we continue to augment our clinical product with expanded report review capabilities, and we have broadened our Opal API to further support high-throughput labs' requirements. We have also upgraded and unified our variant analysis table views across the Opal application, including Variant Miner and VAAST. 

Opal Clinical provides an end-to-end solution for clinical NGS testing, combining Omicia’s industry-leading Opal annotation platform with structured interpretation workflows, full support for clinical report generation, curated gene panels and LIS integration -- all within a secure, HIPAA-compliant environment. Contact sales@omicia.com if you’d like to try Opal Clinical.

Opal Clinical - Review Approved Report Data

Opal Clinical now allows data from approved reports to be reviewed, including reported and unreported variants, as well as internal notes. This new read-only view for approved reports is accessible using the View Interpretation menu option in the Clinical Reports page. 


Upgrades to Variant Analysis Table Views - Clinical Variant Miner, Variant Miner, VAAST and Flex

We have upgraded and unified all of the variant analysis table views in Clinical Variant Miner, Variant Miner, VAAST and Flex.

For those users who also use Opal Clinical, the new variant table views will be familiar as we are now leveraging the same architecture and look and feel as Clinical Reporter. This change accelerates our ability to deliver new capabilities to both our clinical and research users. 

Key enhancements:

  • Comprehensive and consistent filters allow you to filter data using gene symbol, variant type, ClinVar class, allele frequency, coverage, saved Filtering Protocols, Panels and more
  • Simplified Gene Set selection so all available gene sets are selectable from the same menu, and only workspace gene sets are provided
  • Streamlined Genome Operations, allowing you to find shared or unique variants between samples more easily (Variant Miner only)
  • Improved color palette for users with color vision deficiency
  • Mouse-over help for fields and data in the variant table. 

Review Priority Field

A new Review Priority Field has been introduced in the variant table views. The Review Priority field provides three separate color-coded assessments for each variant: ClinVar Classification, Allele Frequency and Effect.

>Review Priority upgrades and replaces Predicted Class, giving the interpreter more detail while still providing a single field for prioritization and sorting. Samples annotated with Opal pipeline 4.4 or greater will display Review Priority. Samples annotated with Opal pipeline 4.3 or lower will not be changed.

More details on Review Priority are available in Appendix 3

Omicia API

The Omicia Opal API continues to be expanded to support high throughput requirements. In this release, we have added support for inclusion of phenotype terms as direct input into the Phevor algorithm for exome and genome tests

Higher-throughput labs will benefit from using the Omicia API to integrate with existing lab systems and automate processes including:

  • Uploading genomes
  • Setting up clinical tests including upload of patient and phenotype information
  • Uploading quality control data from sequencing and/or alignment
  • Sanger confirmation of variants
  • Export of final report results
  • Creation and editing of panels


If you are interested in using the Omicia API in your lab, please contact support@omicia.com.


Annotation Pipeline - tRNA Variants

In our September release, we added annotation support for transcripts for ribosomal DNA in both mitochondrial and nuclear DNA. In this release, we also add annotation support for mitochondrial tRNA variants.
