Microsatellite Instability (MSI)

Microsatellite Instability (MSI) If MSI values are needed ahead of software updates, it is recommend to calculate MSI on the tumor fastq files in tumor-only mode in a separate DRAGEN analysis. Tumor-o

It is recommend to calculate MSI in tumor-only mode. Tumor-only mode relies on a reference directory of files (.dist) containing the microsatellite repeat distribution in a panel of normals. Both the reference directory and microsatellite list are provided - see the Resource Files page for more information - and need to match the reference genome used in the alignment step.
