CheckAlignment

Validates consistency of the aligner interface

Category Diagnostics and Quality Control Tools

Traversal ReadWalker

PartitionBy READ


Overview

Validates consistency of the aligner interface by taking reads already aligned by BWA in a BAM file, stripping them of their alignment data, realigning them, and making sure one of the best resulting realignments matches the original alignment from the input file.

Caveat

This tool requires that BWA be available on the java path.


Additional Information

Read filters

This Read Filter is automatically applied to the data by the Engine before processing by CheckAlignment.

Downsampling settings

This tool does not apply any downsampling by default.

Inherited arguments

The arguments described in the entries below can be supplied to this tool to modify its behavior. For example, the -L argument directs the GATK engine restricts processing to specific genomic intervals (this is an Engine capability and is therefore available to all GATK walkers).
