.. class:: infomark

**What it does**

`Cactus <https://github.com/ComparativeGenomicsToolkit/cactus>`__ is a
reference-free whole-genome multiple alignment program. It can be used
to progressively align a large number of genomes.

-----

.. class:: infomark

**Usage**

**Between-species mode (Progressive Cactus)**

If you are aligning genomes from **multiple species**, you need to
provide a guide tree in Newick format. Cactus uses the guide tree to
progressively align genomes, meaning that it doesn’t need to align all
possible pairs of genomes.

A Newick-formatted tree for human, chimp and gorilla genomes looks like
this:

    ::

        (((human:0.006,chimp:0.006667):0.0022,gorilla:0.008825):0.0096,orang:0.01831);

The numbers are the branch lengths.

**Within-species mode (Minigraph-Cactus)**

You can also run Cactus in `pangenome
mode <https://github.com/ComparativeGenomicsToolkit/cactus/blob/master/doc/pangenome.md>`__
to align genomes of multiple individuals from the **same species**. In
this mode you will not use a guide tree. Cactus will use
`minigraph <https://github.com/lh3/minigraph>`__ to generate a graph of
the input genomes and then use the graph to order the alignments. To use
pangenome mode, select ‘Within-species’ in the ‘Alignment mode’
dropdown.

Unlike Between-species mode, Within-species mode depends on a predetermined reference genome.

-----

.. class:: infomark

**Input**

The developers recommend soft-masking your genomes with RepeatMasker
before running Cactus. RepeatMasker is available on Galaxy.

If you’re using Between-species mode, you need to provide labels for the
fasta files that match the leaves on the guide tree. In the example
above, you would use the label ‘human’ for the human fasta file.

-----

.. class:: infomark

**Output**

The main output of Cactus is in `HAL
format <https://github.com/ComparativeGenomicsToolkit/cactus#using-the-output>`__.
You can use the `Cactus: export <root?tool_id=cactus_export>`__ tool to
convert the Cactus output to a VG or Multiple Alignment Format (MAF)
file.
