NotPrimaryAlignmentFilter

Filter out read records that are secondary alignments

Category Read Filters


Overview

This filter recognizes the SAM flag that identifies secondary alignments. It is intended to ensure that only records that are likely to be mapped in the right place, and therefore to be informative, will be used in analysis. To be clear, it does NOT filter out read records that are supplementary alignments.

Usage example

     java -jar GenomeAnalysisTk.jar \
         -T ToolName \
         -R reference.fasta \
         -I input.bam \
         -o output.file \
         -rf NotPrimaryAlignment
