Introduction
============

What is HISAT?
--------------

`HISAT <http://ccb.jhu.edu/software/hisat>`__ is a fast and sensitive
spliced alignment program. As part of HISAT, we have developed a new
indexing scheme based on the Burrows-Wheeler transform
(`BWT <http://en.wikipedia.org/wiki/Burrows-Wheeler_transform>`__) and
the `FM index <http://en.wikipedia.org/wiki/FM-index>`__, called
hierarchical indexing, that employs two types of indexes: (1) one global
FM index representing the whole genome, and (2) many separate local FM
indexes for small regions collectively covering the genome. Our
hierarchical index for the human genome (about 3 billion bp) includes
~48,000 local FM indexes, each representing a genomic region of
~64,000bp. As the basis for non-gapped alignment, the FM index is
extremely fast with a low memory footprint, as demonstrated by
`Bowtie <http://bowtie-bio.sf.net>`__. In addition, HISAT provides
several alignment strategies specifically designed for mapping different
types of RNA-seq reads. All these together, HISAT enables extremely fast
and sensitive alignment of reads, in particular those spanning two exons
or more. As a result, HISAT is much faster >50 times than
`TopHat2 <http://ccb.jhu.edu/software/tophat>`__ with better alignment
quality. Although it uses a large number of indexes, the memory
requirement of HISAT is still modest, approximately 4.3 GB for human.
HISAT uses the `Bowtie2 <http://bowtie-bio.sf.net/bowtie2>`__
implementation to handle most of the operations on the FM index. In
addition to spliced alignment, HISAT handles reads involving indels and
supports a paired-end alignment mode. Multiple processors can be used
simultaneously to achieve greater alignment speed. HISAT outputs
alignments in `SAM <http://samtools.sourceforge.net/SAM1.pdf>`__ format,
enabling interoperation with a large number of other tools (e.g.
`SAMtools <http://samtools.sourceforge.net>`__,
`GATK <http://www.broadinstitute.org/gsa/wiki/index.php/The_Genome_Analysis_Toolkit>`__)
that use SAM. HISAT is distributed under the `GPLv3
license <http://www.gnu.org/licenses/gpl-3.0.html>`__, and it runs on
the command line under Linux, Mac OS X and Windows.

Running HISAT
=============

Reporting
---------

The reporting mode governs how many alignments HISAT looks for, and how
to report them.

In general, when we say that a read has an alignment, we mean that it
has a `valid
alignment <#valid-alignments-meet-or-exceed-the-minimum-score-threshold>`__.
When we say that a read has multiple alignments, we mean that it has
multiple alignments that are valid and distinct from one another.

Distinct alignments map a read to different places
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Two alignments for the same individual read are "distinct" if they map
the same read to different places. Specifically, we say that two
alignments are distinct if there are no alignment positions where a
particular read offset is aligned opposite a particular reference offset
in both alignments with the same orientation. E.g. if the first
alignment is in the forward orientation and aligns the read character at
read offset 10 to the reference character at chromosome 3, offset
3,445,245, and the second alignment is also in the forward orientation
and also aligns the read character at read offset 10 to the reference
character at chromosome 3, offset 3,445,245, they are not distinct
alignments.

Two alignments for the same pair are distinct if either the mate 1s in
the two paired-end alignments are distinct or the mate 2s in the two
alignments are distinct or both.

Default mode: search for one or more alignments, report each
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

HISAT searches for up to N distinct, primary alignments for each read,
where N equals the integer specified with the ``-k`` parameter. Primary
alignments mean alignments whose alignment score is equal or higher than
any other alignments. It is possible that multiple distinct alignments
whave the same score. That is, if ``-k 2`` is specified, HISAT will
search for at most 2 distinct alignments. The alignment score for a
paired-end alignment equals the sum of the alignment scores of the
individual mates. Each reported read or pair alignment beyond the first
has the SAM 'secondary' bit (which equals 256) set in its FLAGS field.
See the `SAM specification <http://samtools.sourceforge.net/SAM1.pdf>`__
for details.

HISAT does not "find" alignments in any specific order, so for reads
that have more than N distinct, valid alignments, HISAT does not
gaurantee that the N alignments reported are the best possible in terms
of alignment score. Still, this mode can be effective and fast in
situations where the user cares more about whether a read aligns (or
aligns a certain number of times) than where exactly it originated.

Alignment summmary
------------------

When HISAT finishes running, it prints messages summarizing what
happened. These messages are printed to the "standard error" ("stderr")
filehandle. For datasets consisting of unpaired reads, the summary might
look like this:

::

    20000 reads; of these:
      20000 (100.00%) were unpaired; of these:
        1247 (6.24%) aligned 0 times
        18739 (93.69%) aligned exactly 1 time
        14 (0.07%) aligned >1 times
    93.77% overall alignment rate

For datasets consisting of pairs, the summary might look like this:

::

    10000 reads; of these:
      10000 (100.00%) were paired; of these:
        650 (6.50%) aligned concordantly 0 times
        8823 (88.23%) aligned concordantly exactly 1 time
        527 (5.27%) aligned concordantly >1 times
        ----
        650 pairs aligned concordantly 0 times; of these:
          34 (5.23%) aligned discordantly 1 time
        ----
        616 pairs aligned 0 times concordantly or discordantly; of these:
          1232 mates make up the pairs; of these:
