Metagenomic Trees: One method in metagenomic studies is to map sequences reads on a library of reference genomes or proteomes. The result is a phylogenetic tree where each node has a number of reads assigned to it. The usual representations of trees are not adapted to the visualisation of quantities assigned to each node. We developed graphical modules that focus on the specifications of this type of trees.
The following modules use as input, a json file obtained from our MetaBin program.

Projects:

This module implement treemap and table views. It include format convertor and search function. It allows high degree of customisation of colors and labels, synchronized or not with a selected phylogenic rank. Visualisation, configuration and data can be exported to further use.
This module implement a light version of stack, sunburst and treemap view. Both views can be display with specific or synchronized configuration. It allows colors and labels customisations according to selected phylogenic rank. Visualisation, configuration and data can be exported to further use.

Views:

Treemap

A treemap represent a tree as nested rectangles where the area of each rectangle is proportional to the number of assigned reads. By construction, a sub-branch of the tree is also a rectangle with its area proportional to the sum of the reads assigned to this sub-branch.

Table

A table represent a tree a list of nodes. Various information are displayed for each node like number and percentage of hits or phylogenetic rank. In addition collapse/expant option allows to hide/show the sub-nodes of a particular element.

Sunburst

A sunburst represent a tree as stacked arcs. The root is at the center and deeper levels are at incremented radius. The angle of each arc (i.e. the area) is proportional to the number of assigned reads. The area of an internal node in proportional to the sum of the reads assigned to its sub-nodes.

Stack

A stack represent a tree as stacked rectangles. The root is at the bottom and deeper levels are at the top. The width of each rectangle (i.e. the area) is proportional to the number of assigned hits. The length of an internal node in proportional to the sum of the hits assigned to its sub-nodes.
