Met4J is an open-source Java library dedicated to the structural analysis of metabolic networks. It also came with a toolbox gathering CLI for several analyses relevant to metabolism-related research.

Met4j is composed by three main modules:

• met4j-core: it's the key module which contains all the core classes for handling metabolic networks
• met4j-io: for importing/exporting metabolic networks in several formats (SBML, KEGG, TSV)
• met4j-graph: for performing graph-based topological analysis of metabolic networks.

The package met4j-toolbox contains high-level apps that can be run in command line by using either jar file or Singularity or Docker containers.

Install all modules :

<dependency>
<groupId>fr.inrae.toulouse.metexplore</groupId>
<artifactId>met4j-toolbox</artifactId>
<version>1.4.0</version>
</dependency>

or a specific module (example : met4j-core ):

<dependency>
<groupId>fr.inrae.toulouse.metexplore</groupId>
<artifactId>met4j-core</artifactId>
<version>1.4.0</version>
</dependency>

git clone https://forgemia.inra.fr/metexplore/met4j.git;
cd met4j;
mvn clean install 

Read met4j-toolbox to see how to get jar, Docker or Singularity packages containing all the met4-toolbox apps.

User documentation for the library modules can be found in each module's own README.
