Structure of the project

The KAMIStudio repository consists of the following directories:

• kamistudio the main KAMIStudio application package;
• examples a set of example .JSON files that can be used to import a corpus, interactions and a model;
• db a set of database resources needed for configuring Neo4j in the KAMIStudio Docker container.

and the following files:

• setup.py the setup file for python setup.py install;
• configure.py KAMIStudio configuration script for python configure.py;
• run.sh bash script for starting the KAMIStudio app (./run.sh);
• Dockerfile a file containing instructions for assembling a Docker container (see https://docs.docker.com/engine/reference/builder/ for more details on dockerfiles);
• docker-compose.yml a Docker compose file for assembling a multi-container app (one container for the Neo4j db, one for MongoDB and one for the KAMIStudio app, see https://docs.docker.com/compose/ for more details)

Let's have a closer look at the directories:

Package kamistudio

This package is organized as a 'typical' Flask-app that uses blueprints (see a nice article explaining them). It includes the following blueprint packages (and respectively directories):

• home blueprint for the home page showing the list of corpora and models, allowing to create and import one;
• corpus blueprint for the corpus-related functionality: corpus view, addition or import of new interactions, definitions, model instantiation, etc.;
• model blueprint for the model-related functionality: model view, Kappa generation, etc.;
• action_graph blueprint for generic (for both corpora and models) action-graph-related functionality;
• nuggets blueprint for generic (for both corpora and models) nugget-related functionality;
• definitions blueprint for generic (for both corpora and models) protein-definition-related functionality;

Every blueprint package typically contains the directory templates with the blueprint specific Jinja-templates, the directory static with the static files and the file views.py containing all the routes in the blueprint.

Additionally, the KAMIStudio app contains some generic top-level directories:

• static containing generic static files (css/js/images);
• templates containing generic Jinja templates (such as error pages, base.html, etc);
• instance contains instance-specific configurations (see more details here).

Finally, the top-level

• config.py default top-level configurations;
• exceptions.py KAMIStudio custom exceptions;
• utils.py a set of utilities (like checking db connections, etc.);
• __init__.py a file containing the application factory (see more details here).

Folder examples

This folder contains the following files:

• egfr_corpus.json JSON-representation of an example corpus for KAMIStudio import (part of the EGFR signalling pathway);
• egfr_interactions.json JSON-representation of interactions for batch-import;
• egfr_model.json an example model for KAMIStudio import (instantiated EGFR corpus).

Folder db

This folder is used for creating a Docker container for KAMIStudio. It contains some resources needed to properly configure the database containers. It serves a doble-purpose:

1. provides necessary resources (i.e. Neo4j plug-ins an configurations),
2. provides directories where Neo4j and MongoDB will store their data, when container is created.
