**What it does**

 Generate BCF or pileup for one or multiple BAM files. Alignment records are grouped by sample identifiers in @RG header lines. If sample identifiers are absent, each input file is regarded as one sample. 

------

**Settings**::

 Input Options:
 -6 	Assume the quality is in the Illumina 1.3+ encoding.
 -A Do not skip anomalous read pairs in variant calling.
 -B 	Disable probabilistic realignment for the computation of base alignment quality (BAQ). BAQ is the Phred-scaled probability of a read base being misaligned. Applying this option greatly helps to reduce false SNPs caused by misalignments.
 -b FILE 	List of input BAM files, one file per line [null]
 -C INT 	Coefficient for downgrading mapping quality for reads containing excessive mismatches. Given a read with a phred-scaled probability q of being generated from the mapped position, the new mapping quality is about sqrt((INT-q)/INT)*INT. A zero value disables this functionality; if enabled, the recommended value for BWA is 50. [0]
 -d INT 	At a position, read maximally INT reads per input BAM. [250]
 -E 	Extended BAQ computation. This option helps sensitivity especially for MNPs, but may hurt specificity a little bit.
 -f FILE 	The faidx-indexed reference file in the FASTA format. The file can be optionally compressed by razip. [null]
 -l FILE 	BED or position list file containing a list of regions or sites where pileup or BCF should be generated [null]
 -q INT 	Minimum mapping quality for an alignment to be used [0]
 -Q INT 	Minimum base quality for a base to be considered [13]
 -r STR 	Only generate pileup in region STR [all sites]
 Output Options:
 	
 -D 	Output per-sample read depth
 -g 	Compute genotype likelihoods and output them in the binary call format (BCF).
 -S 	Output per-sample Phred-scaled strand bias P-value
 -u 	Similar to -g except that the output is uncompressed BCF, which is preferred for piping.
 
 Options for Genotype Likelihood Computation (for -g or -u):
  	
 -e INT 	Phred-scaled gap extension sequencing error probability. Reducing INT leads to longer indels. [20]
 -h INT 	Coefficient for modeling homopolymer errors. Given an l-long homopolymer run, the sequencing error of an indel of size s is modeled as INT*s/l. [100]
 -I 	Do not perform INDEL calling
 -L INT 	Skip INDEL calling if the average per-sample depth is above INT. [250]
 -o INT 	Phred-scaled gap open sequencing error probability. Reducing INT leads to more indel calls. [40]
 -P STR 	Comma dilimited list of platforms (determined by @RG-PL) from which indel candidates are obtained. It is recommended to collect indel candidates from sequencing technologies that have low indel error rate such as ILLUMINA. [all]

**What it does**

Report variants for one or multiple BAM files. Alignment records are grouped by sample identifiers in @RG header lines. If sample identifiers are absent, each input file is regarded as one sample. 

------

**Input options**::

  -6, --illumina1.3+      quality is in the Illumina-1.3+ encoding
  -A, --count-orphans     do not discard anomalous read pairs
  -b, --bam-list FILE     list of input BAM filenames, one per line
  -B, --no-BAQ            disable BAQ (per-Base Alignment Quality)
  -C, --adjust-MQ INT     adjust mapping quality; recommended:50, disable:0 [0]
  -d, --max-depth INT     max per-BAM depth; avoids excessive memory usage [250]
  -E, --redo-BAQ          recalculate BAQ on the fly, ignore existing BQs
  -f, --fasta-ref FILE    faidx indexed reference sequence file
  -G, --exclude-RG FILE   exclude read groups listed in FILE
  -l, --positions FILE    skip unlisted positions (chr pos) or regions (BED)
  -q, --min-MQ INT        skip alignments with mapQ smaller than INT [0]
  -Q, --min-BQ INT        skip bases with baseQ/BAQ smaller than INT [13]
  -r, --region REG        region in which pileup is generated
  -R, --ignore-RG         ignore RG tags (one BAM = one sample)
  --rf, --incl-flags STR|INT  required flags: skip reads with mask bits unset []
  --ff, --excl-flags STR|INT  filter flags: skip reads with mask bits set
                                            [UNMAP,SECONDARY,QCFAIL,DUP]
  -x, --ignore-overlaps   disable read-pair overlap detection

**Output options**::

  -o, --output FILE       write output to FILE [standard output]
  -g, --BCF               generate genotype likelihoods in BCF format
  -v, --VCF               generate genotype likelihoods in VCF format

**Output options for mpileup format** (without -g/-v)::

  -O, --output-BP         output base positions on reads
  -s, --output-MQ         output mapping quality

**Output options for genotype likelihoods** (when -g/-v is used)::

  -t, --output-tags LIST  optional tags to output: DP,DPR,DV,DP4,INFO/DPR,SP []
  -u, --uncompressed      generate uncompressed VCF/BCF output

**SNP/INDEL genotype likelihoods options** (effective with -g/-v)::

  -e, --ext-prob INT      Phred-scaled gap extension seq error probability [20]
  -F, --gap-frac FLOAT    minimum fraction of gapped reads [0.002]
  -h, --tandem-qual INT   coefficient for homopolymer errors [100]
  -I, --skip-indels       do not perform indel calling
  -L, --max-idepth INT    maximum per-sample depth for INDEL calling [250]
  -m, --min-ireads INT    minimum number gapped reads for indel candidates [1]
  -o, --open-prob INT     Phred-scaled gap open seq error probability [40]
  -p, --per-sample-mF     apply -m and -F per-sample for increased sensitivity
  -P, --platforms STR     comma separated list of platforms for indels [all]

**Notes**: Assuming diploid individuals.
