Opal 4.22 Release Notes

Jeanette McCarthy -

31 August 2016

Opal 4.22 is live! In this release, we provide a direct curation interface to the Classified Variant Database, and deliver improved error handling for VCF data. 

Opal Clinical provides an end-to-end solution for clinical NGS testing, combining Omicia’s industry-leading Opal annotation platform with structured workflows, integrated ACMG-guided classification, full support for clinical report generation and LIS integration -- all within a secure, HIPAA-compliant environment. Opal Clinical has been extended to support somatic cancer testing, enabling labs to use one interpretation platform for hereditary and somatic NGS testing. Contact sales@omicia.com if you’d like to try Opal Clinical.


Classified Variant Database

Improved Error Handling for VCFs

Data Source & Algorithm Versions


Classified Variant Database

Opal builds the Classified Variant Database automatically as variants are classified and reports are signed out by your lab. Data on previously classified variants is seamlessly accessible when variants are seen again in a new patient. Existing classifications as well as variant descriptions can be easily applied to new reports, and this can be automated for high-volume panels. The Classified Variant Database accelerates interpretation and improves standardization.

Opal 4.22 provides a direct interface to the Classified Variant Database, enabling review of current and previous variant classifications as well as ACMG scoring criteria. In addition, administrators can retire outdated classifications as needed. The Classified Variant Database is accessible from the Opal Home Page.


Improved Error Handling for VCFs

Opal Clinical's VCF upload feature follows VCF format standards. Documentation is provided in Appendix 1. We recognize that some files may not fully adhere to the VCF standard, and a lab may still desire to use these files for validation or related purposes. We have introduced improved error handling in this release. Now, Opal will not fail files with errors, such as erroneous reference bases. Instead, Opal will indicate that the file had errors in the Variant Report and the Clinical Report. Opal will also highlight all variants with issues in the variant table. This detailed information enables labs to identify and resolve VCF issues, and enables them to continue with some aspects of their validation work.
