BamUtil: indelDiscordance

Overview of the indelDiscordance function of bamUtil

The indelDiscordance option on the bamUtil looks at discordance at sites on the male X chromosome.

Usage

./bam indelDiscordance --in <inputFile> [--bamIndex <bamIndexFile] [--refFile <filename>] [--umRef] [--depth minDepth] [--minRepeatLen len] [--sumRepeatLen len] [--printPos] [--chrom <name>] [--start 0basedPos] [--end 0basedPos] [--noeof] [--params]

Parameters

	Required Parameters:
		--in : the SAM/BAM file to calculate indelDiscordance for
	Optional Parameters:
		--bamIndex     : The path/name of the bam index file
		                 (if required and not specified, uses the --in value + ".bai")
		--refFile      : reference file for determining repeat counts
		--umRef        : use the reference at the default UofM location, 		                 /data/local/ref/karma.ref/human.g1k.v37.umfa
		--depth        : min depth at which to report indel discordance, DEFAULT >= 2
		--minRepeatLen : min repeat length for printing repeat info, DEFAULT = 1
		--sumRepeatLen : all repeats this length and longer will be accumulated,
		                 DEFAULT = 5
		--printPos     : print details for each position
		--chrom        : chromosome name other than X
		--start        : use a 0-based inclusive start position other than the default, 2699520
		--end          : use a 0-based exclusive end position other than the default, 154931043
		--noeof        : Do not expect an EOF block on a bam file.
		--params       : Print the parameter settings

Input File (--in)

Use --in followed by your file name to specify the SAM/BAM input file.

The program automatically determines if your input file is SAM/BAM/uncompressed BAM without any input other than a filename from the user, unless your input file is stdin.

A - is used to indicate to read from stdin and the extension is used to determine the file type (no extension indicates SAM).

SAM/BAM/Uncompressed BAM from file	--in yourFileName
SAM from stdin	--in -
BAM from stdin	--in -.bam
Uncompressed BAM from stdin	--in -.ubam

Note: Uncompressed BAM is compressed using compression level-0 (so it is not an entirely uncompressed file). This matches the samtools implementation so pipes between our tools and samtools are supported.

Bam Index File (--bamIndex)

Use --bamIndex followed by your file name to specify the BAM index file to use for reading the BAM file.

If this file is required but not specified, it will use the input file name + ".bai".

Reference File (--refFile)

Use --refFile followed by the reference file name to specify the reference sequence file.

Do not require BGZF EOF block (--noeof)

Use --noeof if you do not expect a trailing eof block in your bgzf file.

By default, the trailing empty block is expected and checked for.

Print the Program Parameters (--params)

Use --params to print the parameters for your program to stderr.

Output

All status messages are written to stderr.
