Introduction

The Artemis Software includes:

• Artemis
• ACT
• BamView
• DNAPlotter

Artemis is a free genome browser and annotation tool that allows visualisation of sequence features, next generation data and the results of analyses within the context of the sequence, and also its six-frame translation. Artemis is written in Java, and is available for UNIX, Macintosh and Windows systems. It can read EMBL and GENBANK database entries or sequence in FASTA, indexed FASTA or raw format. Other sequence features can be in EMBL, GENBANK or GFF format.

ACT is a free tool for displaying pairwise comparisons between two or more DNA sequences. It can be used to identify and analyse regions of similarity and difference between genomes and to explore conservation of synteny, in the context of the entire sequences and their annotation.

DNAPlotter generates images of circular and linear DNA maps.

BamView is a standalone BAM/CRAM file viewer.

Prerequisites

Java version 9 or later must be installed. Ideally Java 11 should be used. The easiest way to install a non-commercial open source Java version is from AdoptOpenJDK - just select the OpenJDK 11 and Hotspot options for the relevant platform. See the GitHub pages and manuals for further options. A Java installation is not required if installing via Bioconda or Docker.

Installation

Please refer to the relevant documentation in the Documentation section below.

Usage

Please refer to the relevant documentation in the Documentation section below.

Building

If you would prefer to build the applications from scratch rather than use the pre-built releases, then you will firstly need the source code from GitHub. This can be obtained by cloning the repository:

git clone https://github.com/sanger-pathogens/Artemis.git

or by downloading the source zip file for a particular release. The latest version of Apache Maven (Java 11 compatible, e.g. v3.6.0) will need to be installed beforehand, in order to build. The application jars can be built by issuing the following commands in the top-level folder:

When building for the first time:

mvn validate

This is required to install some legacy libraries to the Maven repository and will be phased out in future releases.

And then to build/rebuild the applications:

mvn clean package

Clean is only required if you wish to do a complete rebuild. If you do not wish to run tests then add the -Dskip.tests=true flag to the above command.

Note that if you are running a build from behind a proxy you will need to add the proxy parameters to the mvn command line, e.g.

mvn -Dhttps.proxyHost=myproxyhost -Dhttps.proxyPort=myproxyport -DproxySet=true package

This will build the application jars and place them in target/jars and win-jars folders. The win-jars jars have the etc folder files bundled in, for Windows.

Building Release Artifacts

To build .zip or .gz installables with unsigned jars, use the following command:

mvn -Djarsigner.skip=true clean package -P release

If building on a Mac then .app packages and a .dmg image can additionally be produced using:

mvn -Djarsigner.skip=true clean package verify -P release

The release artifacts can then be found in the target/release-artifacts directory.

Jar signing can be included in the build cycle by not supplying a -Djarsigner.skip flag. A maven.properties file needs to be placed in the top-level Artemis folder containing the following keystore properties:

signer-keystore-path=<The path to a .jks keystore>
signer-keystore-alias=<certificate alias name>
signer-keystore-password=<keystore password>
signer-keystore-type=JKS

Searching and Using Local Sequence Databases

Artemis and ACT can optionally be used with local sequence databases on non-Windows systems.

[Note: this may require a lot of disk space]

If you wish to do this then carry out the following steps:

1. To download and install BLAST+ locally, check here:

ftp://ftp.ncbi.nlm.nih.gov/blast/executables/blast+/LATEST/

to get the latest Mac OS X release:

ftp://ftp.ncbi.nlm.nih.gov/blast/executables/blast+/LATEST/ncbi-blast-2.7.1+-x64-macosx.tar.gz

Uncompress, if you have downloaded a .tar.gz, e.g.

tar -zxvf ncbi-blast-2.7.1+-x64-macosx.tar.gz

For a Mac OS X install you can mount the resulting .dmg image by double-clicking it and then selecting the .pkg installer file to actually install the BLAST+ executables into the default location (/usr/local/ncbi/blast). Comprehensive installation instructions for all operating systems are provided here.

2. Ensure that the BLAST+ executables are available in your PATH and that local databases can be found by Artemis:

On the command line type:

blastp -help

If the executables are not found then their installation bin folder will need to be added to your .profile PATH variable. This can be achieved by uncommenting and setting the relevant environment variables in the Variables for locally installed Blast databases section of the Artemis setenv script. The location of the databases is assumed by default to be <home directory>/blast-data but this can be overridden by setting the BLASTDB variable (See Blast+ documentation). The setenv script should then be called from your login .profile file. Alternatively copy the relevant variables into your profile.

Note that database locations can also be specified directly within the Artemis/ACT applications using the run menu - set options functionality.

4. Download and format the uniprot database(s):

You can do this by using the Artemis etc/setup_uniprot_dbs.sh script. This script can be changed as desired, to for instance, include additional databases.

mkdir $HOME/blast-data
cd blast-data
cp <Artemis folder>/etc/setup_blast_dbs.sh .
./setup_blast_dbs.sh

(Note: the environment variable http_proxy may need to be set for the ftp downloads to work).
