====== Pathway viewer ======

A pathway viewer has been develop in order to make easier the visualization of the comparison results.

{{ :pathwayviewer1.png?800 |}}

You can select the pathway to see in the //Pathways list// (**1**).
You can also visualize a single circuit by clicking on its name (**3**) in the //Available circuits// list (**2**). Circuits depicted in blue are significantly down-regulated circuits whereas those depicted in red are significantly up-regulated ones (p-value = 0.05). Circuits depicted in grey are not significant.

===== Legend =====
{{ ::metabolizer_legend.png?300 |}}

The information summarized in the pathway viewer includes:

Node's shape:
  * **Rectangles** correspond to metabolic enzymatic.
  * **Circles** represent metabolites.

Node's color:
  * **Blue** for down-regulated reactions, **red** for up-regulated reactions and **grey** for not significant genes.
  * The intensity of the color depends on the significance of the differential expression.

Edge's shape: Edges represent direction of the production by classic arrows.
  * Also gives information about reversible and irreversible reactions

Edge's color:
  * Modules which are **up-regulated** in the disease condition have their arrows colored in **red**.
  * Modules which are **down-regulated** in the disease condition have their arrows colored in **blue**. 
  * Modules which are **not significant** for the test have their arrows colored in **grey**.
