View tumor mutational burden analysis results
You can view the results and calculated tumor mutational burden (TMB mutations/Mb) when you open analysis results that used a workflow with tumor mutational burden enabled.
- Click the Analyses tab.
- In the Overview screen, use the Workflow filter to limit the list of analyses to limit the list of analyses that use an Oncomine™ Tumor Mutation Load workflow.
- Click a row in the Analyses table to view the Details of the analysis.
In the Details pane you can view Workflow Details, and access the Actions list.
- Click the link for the name of the Analysis to open the Analysis Results screen.
The Analysis Results screen opens to the Oncomine tab that displays displaying variants that are annotated with Oncomine™ annotated variants that are relevant to cancer with Oncomine™ Gene Class and Oncomine™ Variant Class information.
Information for tumor mutational burden that is displayed at the top of the Analysis Results screen is as follows.
Item
Description
The value of the result for the tumor mutational burden calculation.
For more information, see Example: Tumor Mutational Burden calculation.
A score of High, Intermediate, or Low.
Thresholds to determine the TMB classification are set with the TMB-Low Threshold and TMB-High Threshold parameters. For more information, see Annotation parameters.
A classification status of Undefined indicates that either the TMB classification thresholds settings were not included in the analysis workflow or were set incorrectly.
- In the Analysis Results table, sort or filter the data using the Oncomine™-specific annotations.
- The default Filter Chain is Oncomine Variants, which runs the Oncomine™ Variant Annotator plugin, a plugin that integrates data from more than 24,000 exomes across solid tumor and hematological cancer types and annotates variants relevant to cancer research with Oncomine™ Gene Class and Oncomine™ Variant Class information. For a variant to be filtered in on the results, the variant that is called must meet all the criteria for the filter chain. For more information, see Predefined filter chains.
Select No Filter to view all the variant calls attempted by the variant caller.
If you save a filter chain other than Oncomine Variants (5.12), changes can occur to the variant calls that are saved in the VCF file and can affect results for downstream processes, such as the results in Oncomine™ Reporter Software.
- In the Oncomine tab, click the column headings to sort the list of variants by Oncomine Variant Class or Oncomine Gene Class.
- The default Filter Chain is Oncomine Variants, which runs the Oncomine™ Variant Annotator plugin, a plugin that integrates data from more than 24,000 exomes across solid tumor and hematological cancer types and annotates variants relevant to cancer research with Oncomine™ Gene Class and Oncomine™ Variant Class information. For a variant to be filtered in on the results, the variant that is called must meet all the criteria for the filter chain. For more information, see Predefined filter chains.
- To download a results file.
- Click Download , then select All Variants, Filtered Variants, Selected Variants or Current Results TSV.
For more information on the downloads, see Download filtered variants.
- In the Home tab, click Notifications, then click
next to the file name. Alternatively, select one or more rows, then click Download.
- Click Download , then select All Variants, Filtered Variants, Selected Variants or Current Results TSV.
The software generates a ZIP file with 4 folders: RESULTS, QC, Variants, and Workflow_Settings.
