Emulates the samtools pileup command to print aligned reads
Prints the alignment in something similar to the Samtools pileup format (see the Pileup format documentation for more details about the original format). There is one line per genomic position, listing the chromosome name, coordinate, reference base, read bases, and read qualities. In addition to these default fields, additional information can be added to the output as extra columns; see options detailed below.
samtools pileup -f in.ref.fasta -l in.site_list input.bam
A BAM file and the interval to print.
Alignment of reads formatted in the Pileup style.

These Read Filters are automatically applied to the data by the Engine before processing by Pileup.
This tool can be run in multi-threaded mode using these options.
This tool applies the following downsampling settings by default.
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 more details on each argument, see the list further down below the table or click on an argument name to jump directly to that entry in the list.
|Argument name(s)||Default value||Summary|
||NA||ROD file containing metadata|
|NA||An output file created by the walker. Will overwrite contents if file exists|
|NA||Add an extra verbose section to the pileup output|
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.
ROD file containing metadata
This enables annotating the pileup to show overlaps with metadata from a ROD file. For example, if you provide a VCF and there is a SNP at a given location covered by the pileup, the pileup output at that position will be annotated with the corresponding source ROD identifier.
--metadata binds reference ordered data. This argument supports ROD files of the following types: BCF2, BEAGLE, BED, BEDTABLE, EXAMPLEBINARY, GELITEXT, OLDDBSNP, RAWHAPMAP, REFSEQ, SAMPILEUP, SAMREAD, TABLE, VCF, VCF3
An output file created by the walker. Will overwrite contents if file exists
Add an extra verbose section to the pileup output
In addition to the standard pileup output, adds 'verbose' output too. The verbose output contains the number of spanning deletions, and for each read in the pileup it has the read name, offset in the base string, read length, and read mapping quality. These per read items are delimited with an '@' character.
