Overview

CellBase is a scalable and high-performance NoSQL database that integrates relevant biological information from well-known data sources such as Ensembl, Uniprot, IntAct or ClinVar among others. All this data can be queried through a comprehensive RESTful web services API or using the command line interface. Also, a built-in variant annotator has been developed and can be used to annotate files containing variants in Variant Call Format (VCF).

CellBase not only consumes multiple data sources, but has also been designed to run on different database engines. So far, a MongoDB plugin has been fully developed, providing amazing performance and scalability.

CellBase constitutes the knowledge-base component of OpenCB initiative. It is used by other OpenCB projects such as OpenCGA as well as other external applications such as EMBL-EBI EVA or Babelomics.

Note: This repository is a major refactoring of https://github.com/opencb-cloud. All users, please update to this one.

Documentation

You can find CellBase documentation and tutorials at: https://github.com/opencb/cellbase/wiki.

For documenting RESTful web services Swagger has been set-up and is available at http://bioinfo.hpc.cam.ac.uk/cellbase/webservices/.

Issues Tracking

You can report bugs or request new features at GitHub issue tracking.

Release Notes and Roadmap

Releases notes are available at GitHub releases.

Roadmap is available at GitHub milestones. You can report bugs or request new features at GitHub issue tracking.

Versioning

CellBase is versioned following the rules from Semantic versioning.

Maintainers

We recommend to contact CellBase developers by writing to OpenCB mailing list opencb@googlegroups.com. The main developers and maintainers are:

Contributing

CellBase is an open-source and collaborative project. We appreciate any help and feeback from users, you can contribute in many different ways such as simple bug reporting and feature request. Dependending on your skills you are more than welcome to develop client tools, new features or even fixing bugs.

How to build

CellBase is mainly developed in Java and it uses Apache Maven as building tool. CellBase requires Java 8+ and others OpenCB Java dependencies that can be found in Maven Central Repository.

Stable releases are merged and tagged at master branch, you are encourage to use latest stable release for production. Current active development is carried out at develop branch, only compilation is guaranteed and bugs are expected, use this branch for development or for testing new functionalities. Only dependencies of master branch are ensured to be deployed at Maven Central Repository, develop branch may require users to download and install other active OpenCB repositories:

Cloning

CellBase is an open-source and free project, you can download develop branch by executing:

imedina@ivory:~$ git clone https://github.com/opencb/cellbase.git
Cloning into 'cellbase'...
remote: Counting objects: 13804, done.
remote: Compressing objects: 100% (619/619), done.

Resolving deltas: 100% (5049/5049), done.

Latest stable release at master branch can be downloaded executing:

imedina@ivory:~$ git clone -b master https://github.com/opencb/cellbase.git

Build

In case the CellBase installation requires to access a self-maintained installation of the CellBase database, database connection credentials must be set. We use maven to inject the credential values, you need to add this maven configuration to the profiles section at your ~.m2/settings.xml, you may need to change these values according to your particular installation:

<profile>
 <id>localhost</id>
 <activation>
   <activeByDefault>true</activeByDefault>
 </activation>
 <properties>
   <CELLBASE.DB.HOST>localhost:27017</CELLBASE.DB.HOST>
   <CELLBASE.DB.PORT>27017</CELLBASE.DB.PORT>
   <CELLBASE.DB.USER></CELLBASE.DB.USER>
   <CELLBASE.DB.PASSWORD></CELLBASE.DB.PASSWORD>
   <CELLBASE.DB.MONGODB.AUTHENTICATIONDATABASE>admin</CELLBASE.DB.MONGODB.AUTHENTICATIONDATABASE> 
   <CELLBASE.DB.MONGODB.READPREFERENCE>nearest</CELLBASE.DB.MONGODB.READPREFERENCE> 
   <CELLBASE.VERSION>v3</CELLBASE.VERSION> 
   <CELLBASE.ENSEMBL.LIBS>/home/imedina/apis/ensembl/api_79</CELLBASE.ENSEMBL.LIBS> 
   <CELLBASE.DB.MONGODB.REPLICASET></CELLBASE.DB.MONGODB.REPLICASET>
 </properties>
 </profile>

Now you can build CellBase by executing the following command from the root of the cloned repository:

$ mvn clean install -DskipTests

Remember that develop branch dependencies are not ensured to be deployed at Maven Central, you may need to clone and install develop branches from OpenCB biodata and datastore repositories. After this you should have this file structure in cellbase-app/build:

cellbase/build/
├── bin
├── cellbase.war
├── configuration.json
├── example
├── libs
├── LICENSE
├── mongodb-scripts
└── README.md

You can copy the content of the build folder into any directory such as /opt/cellbase.

Testing

You can run the unit tests using Maven or your favorite IDE. Just notice that some tests may require of certain database back-ends such as MongoDB and may fail if they are not available.

Command Line Interface (CLI)

If the build process has gone well you should get an integrated help by executing:

./bin/cellbase.sh --help

As you can see there are four commands implemented, each of them with different options:

  • download: this command downloads the data form different sources such as Ensembl or Uniprot to build CellBase
  • build: with this command you can run the pipelines to create the data models to be loaded into the database
  • load: this command reads the data models and convert and load them into the database
  • query: with this command you can execute queries to CellBase regardless the database used and also you can perform a variant annotation

You can find more detailed documentation and tutorials at: https://github.com/opencb/cellbase/wiki.

Other Dependencies

We try to improve the user experience by making the installation and build as simple as possible. Unfortunately, for some CellBase commands such as build and load other dependencies are required.

Building data

We have developed fast and efficient algorithms to build almost all data models from Ensembl raw data or dumps. But CellBase still depends on Ensembl Perl API for building some specific data models, this can be installed following this tutorial:

http://www.ensembl.org/info/docs/api/api_installation.html
Loading data

At this moment the only fully developed storage engine plugin is MongoDB. MongoDB is free and open-source and can be downloaded from here.
