**What it does**

Converts the HAL output from `Cactus whole-genome multiple sequence
aligner <root?tool_id=cactus_cactus>`__ into other formats.

**Input**

A `HAL
file <https://github.com/ComparativeGenomicsToolkit/cactus#using-the-output>`__
from `Cactus <root?tool_id=cactus_cactus>`__.

**Output**

Currently, you can export a pangenome in VG format, for use with
`vg <https://github.com/vgteam/vg>`__, or Multiple Alignment Format
(MAF). Note that these files are **reference-based**, so it will contain
alignments to a single reference from your list of inputs (i.e. not a
graph). You have to provide this with the ‘reference genome’ option.

You can also export an Assembly Hub for use with the UCSC Genome Browser.
