Collect read length statistics
This tool generates a table with the read lengths categorized per sample. If the file has no sample information (no read groups) it considers all reads to come from the same sample.
A BAM file.
A human/R-readable table of tab-separated values with one column per sample and one row per read.
java -jar GenomeAnalysisTK.jar \ -T ReadLengthDistribution \ -R reference.fasta \ -I example.bam \ -o example.tbl
These Read Filters are automatically applied to the data by the Engine before processing by ReadLengthDistribution.
This tool does not apply any downsampling by default.
All tools inherit arguments from the GATK Engine' "CommandLineGATK" argument collection, which can be used to modify various aspects of the tool's function. For example, the -L argument directs the GATK engine to restrict processing to specific genomic intervals; or the -rf argument allows you to apply certain read filters to exclude some of the data from the analysis.
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|
|stdout||An output file created by the walker. Will overwrite contents if file exists|
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.
