Left-aligns indels from reads in a bam file.
LeftAlignIndels is a tool that takes a bam file and left-aligns any indels inside it. The same indel can often be placed at multiple positions and still represent the same haplotype. While a standard convention is to place an indel at the left-most position this doesn't always happen, so this tool can be used to left-align them.

This Read Filter is automatically applied to the data by the Engine before processing by LeftAlignIndels.
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).
This table summarizes the command-line arguments that are specific to this tool. For details, see the list further down below the table.
Arguments in this list are specific to this tool. Keep in mind that other arguments are available that are shared with other tools (e.g. command-line GATK arguments); see Inherited arguments above.
