Cactus
======

This suite contains a wrapper for the
`Cactus <github.com/comparativeGenomicsToolkit/cactus>`__ whole-genome
aligner and another wrapper for exporting the data it generates.

Requirements
------------

The developers provide an official Docker container. However, the Docker
container won’t run unless ``/etc/passwd`` is mounted (`see this
issue <https://github.com/ComparativeGenomicsToolkit/cactus/issues/677>`__).
Because of this, it is recommended to run Cactus using Singularity.

Cactus uses a lot of RAM. We have tested it on Galaxy using 24 GB of RAM
for a progressive alignment of three chromosome-level, 150 megabase
genomes.
