+
+**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]
