+Output uncompressed BAM. This option saves time spent on
+compression/decomprssion and is thus preferred when the output is piped
+to another samtools command.

+
+Text alignment viewer (based on the ncurses library). In the viewer,
+press `?' for help and press `g' to check the alignment start from a
+region in the format like `chr10:10,000,000' or `=10,000,000' when
+viewing the same reference sequence.

+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.

+.B OPTIONS:
+.RS
+.TP 8
+.B -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.
+.TP
+.BI -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]
+.TP
+.BI -e \ INT
+Phred-scaled gap extension sequencing error probability. Reducing
+.I INT
+leads to longer indels. [20]
+.TP
+.B -E
+Extended BAQ computation. This option helps sensitivity especially for MNPs, but may hurt
+specificity a little bit.
+.TP
+.BI -f \ FILE
+The reference file [null]
+.TP
+.B -g
+Compute genotype likelihoods and output them in the binary call format (BCF).
+.TP
+.BI -h \ INT
+Coefficient for modeling homopolymer errors. Given an
+.IR l -long
+homopolymer
+run, the sequencing error of an indel of size
+.I s
+is modeled as
+.IR INT * s / l .
+[100]
+.TP
+.BI -l \ FILE
+File containing a list of sites where pileup or BCF is outputted [null]
+.TP
+.BI -o \ INT
+Phred-scaled gap open sequencing error probability. Reducing
+.I INT
+leads to more indel calls. [40]
+.TP
+.BI -P \ STR
+Comma dilimited list of platforms (determined by
+.BR @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]
+.TP
+.BI -q \ INT
+Minimum mapping quality for an alignment to be used [0]
+.TP
+.BI -Q \ INT
+Minimum base quality for a base to be considered [13]
+.TP
+.BI -r \ STR
+Only generate pileup in region
+.I STR
+[all sites]
+.TP
+.B -u
+Similar to
+.B -g
+except that the output is uncompressed BCF, which is preferred for piping.

+.B reheader
+samtools reheader <in.header.sam> <in.bam>
+
+Replace the header in
+.I in.bam
+with the header in
+.I in.header.sam.
+This command is much faster than replacing the header with a
+BAM->SAM->BAM conversion.
