Welcome to CENAPT Navigator

What is this tool?

CENAPT Navigator is a compilation of resources related to Natural Product Research and Pharmacognosy. It includes resources on molecular structures, biological activities, spectroscopic data, bibliography, genetics, diseases, pathways, metabolomics…

Who is behind it?

The Center for Natural Product Technologies (CENAPT) offers this tool to the community, as part of our mission to identify and address the major challenges in Natural Product research, and to connect scientists with established and emerging technologies.

How do I use it?

The button on the top of the page contains a tutorial and the detailed explanations of the different features of this tool.

How does it work?

Based on Semantic web and Linked Data technologies, the Resources are connected if they link to each other. These Resources are also characterized by Tags that indicates their purpose, features and characteristics. Using these semantic web notation and visual networking using Cytoscape.js, we are able to provide you with a way to navigate between all the resources present in this system by any entry point of your interest.

Use of the Graph system
This system display the Resources as nodes linked together by edges.
Click on the node of interest to display its informations on the left, you can scroll and move using mouse or fingers. Related nodes (resources and tags) can be fetched and included in the graph using Used to recenter the graph and scale it so it uses the whole visible area.
Used to show/hide the tags.
Used to show/hide the resources.
Used to reorganize the visible nodes to reduce clutter on the graph.
Reorganize the nodes using a more powerful algorithm, on big graphs it can take some time.
Remove all the nodes. Be careful, this cannot be undone yet. So you will have to reload a
resource
from the left sidebar.
Remove the selected node.
Expand the selected node, it will gather the databases linked to that one togething with their related tags.
Start a new graph from the currently selected node.
Display the simple help on top of the graph.

Your graph is empty.
Please click on the top left icon then on the button of a resource.

Help

The interface

The Main Menu

The main element of the interface is the top menu bar, it allows you to navigate through all the sections of CENAPT NAVIGATOR.

Menu bar

The second-most important elements are the sidebars, they can be activated by using the left-most and right-most buttons of the menu

Sidebars buttons

The List of resources sidebar

List sidebar

You can use this side bar to search through the resources, interact with them, especially sending them to the graph tool, adding them to an existing graph, removing them from a graph, or simply looking at the details of this resource.

The resources are sorted in a tree-like structure, so you can have an idea of the category of resource directly from the list

The Details sidebar

Details of a tag

Detail of a tag

Tags (also called Knowledge tags) are meta-information about a resource. They are used to categorize, and classify the different resources.

For example, if a resource contains NMR data, it will be tagged with the
NMR
tag.
The Tags in CENAPT NAVIGATOR are hierarchical (and for semantic web aware users have a transitive inference). This mean that if a resource is tagged with
COSY
, it will also automatically be tagged with
2D NMR
. e.g.
Transitive tags

Details of resources

The Detail sidebar give you information about the currently selected node. That's where you'll find the URL and the description of any object.
