umi_tools dedup - Deduplicate reads based on their UMI
======================================================

Purpose
-------

The purpose of this command is to deduplicate BAM files based on the first
mapping co-ordinate and the UMI attached to the read. It is assumed that the
FASTQ files were processed with extract_umi.py before mapping and thus the UMI
is the last word of the read name. e.g:

@HISEQ:87:00000000_AATT

where AATT is the UMI sequeuence.

If you have used an alternative method which does not separate the
read id and UMI with a "_", such as bcl2fastq which uses ":", you can
specify the separator with the option "--umi-separator=<sep>",
replacing <sep> with e.g ":".

Alternatively, if your UMIs are encoded in a tag, you can specify this
by setting the option --extract-umi-method=tag and set the tag name
with the --umi-tag option. For example, if your UMIs are encoded in
the 'UM' tag, provide the following options:
"--extract-umi-method=tag --umi-tag=UM"

The start postion of a read is considered to be the start of its alignment
minus any soft clipped bases. A read aligned at position 500 with
cigar 2S98M will be assumed to start at postion 498.


Methods
-------

dedup can be run with multiple methods to identify groups of reads with
the same (or similar) UMI(s). All methods start by identifying the
reads with the same mapping position.

The simpliest method, "unique", groups reads with the exact same
UMI. The network-based methods, "cluster", "adjacency" and
"directional", build networks where nodes are UMIs and edges connect
UMIs with an edit distance <= threshold (usually 1). The groups of
reads are then defined from the network in a method-specific manner.

  "unique"
      Reads group share the exact same UMI

  "percentile"
      Reads group share the exact same UMI. UMIs with counts < 1% of the
      median counts for UMIs at the same position are ignored.

  "cluster"
      Identify clusters of connected UMIs (based on hamming distance
      threshold). Each network is a read group

  "adjacency"
      Cluster UMIs as above. For each cluster, select the node(UMI)
      with the highest counts. Visit all nodes one edge away. If all
      nodes have been visted, stop. Otherise, repeat with remaining
      nodes until all nodes have been visted. Each step
      defines a read group.

  "directional" (default)
      Identify clusters of connected UMIs (based on hamming distance
      threshold) and umi A counts >= (2* umi B counts) - 1. Each
      network is a read group.

Options
-------

--extract-umi-method (choice)
      How are the UMIs encoded in the read?

      Options are:

      - "read_id" (default)
            UMIs contained at the end of the read separated as
            specified with --umi-separator option

      - "tag"
            UMIs contained in a tag, see --umi-tag option

--umi-separator (string)
      Separator between read id and UMI. See --extract-umi-method above

--umi-tag (string)
      Tag which contains UMI. See --extract-umi-method above

--edit-distance-threshold (int)
       For the adjacency and cluster methods the threshold for the
       edit distance to connect two UMIs in the network can be
       increased. The default value of 1 works best unless the UMI is
       very long (>14bp)

--paired
       BAM is paired end - output both read pairs. This will also
       force the use of the template length to determine reads with
       the same mapping coordinates.

--spliced-is-unique
       Causes two reads that start in the same position on the same
       strand and having the same UMI to be considered unique if one is
       spliced and the other is not. (Uses the 'N' cigar operation to test
       for splicing)

--soft-clip-threshold (int)
       Mappers that soft clip, will sometimes do so rather than mapping a
       spliced read if there is only a small overhang over the exon
       junction. By setting this option, you can treat reads with at least
       this many bases soft-clipped at the 3' end as spliced.

--multimapping-detection-method (string, choice)
       If the sam/bam contains tags to identify multimapping reads, you can
       specify for use when selecting the best read at a given loci.
       Supported tags are "NH", "X0" and "XT". If not specified, the read
       with the highest mapping quality will be selected

--read-length
      Use the read length as as a criteria when deduping, for e.g sRNA-Seq

--whole-contig
      Consider all alignments to a single contig together. This is useful if
      you have aligned to a transcriptome multi-fasta

--subset (float, [0-1])
      Only consider a fraction of the reads, chosen at random. This is useful
      for doing saturation analyses.

--chrom
      Only consider a single chromosome. This is useful for debugging purposes

--per-contig (string)
      Deduplicate per contig (field 3 in BAM; RNAME).
      All reads with the same contig will be
      considered to have the same alignment position. This is useful
      if your library prep generates PCR duplicates with non identical
      alignment positions such as CEL-Seq. In this case, you would
      align to a reference transcriptome with one transcript per gene

--per-gene (string)
      Deduplicate per gene. As above except with this option you can
      align to a reference transcriptome with more than one transcript
      per gene. You need to also provide --gene-transcript-map option.
      This will also add a metacontig ('MC') tag to the reads if used
      in conjunction with --output-bam

--gene-transcript-map (string)
      File mapping genes to transripts (tab separated), e.g:

      gene1   transcript1
      gene1   transcript2
      gene2   transcript3

--gene-tag (string)
      Deduplicate per gene. As per --per-gene except here the gene
      information is encoded in the bam read tag specified so you do
      not need to supply --gene-transcript-map

--output-bam (string, filename)
      Output a tagged bam file to stdout or -S <filename>

-i, --in-sam/-o, --out-sam
      By default, inputs are assumed to be in BAM format and output are output
      in BAM format. Use these options to specify the use of SAM format for
      inputs or outputs.

-I    (string, filename) input file name
      The input file must be sorted and indexed.

-S    (string, filename) output file name

-L    (string, filename) log file name
