The overlap also has a filter that will allow the user to hide reactions that have zero value flux.

Another type of overlaps was also developed to visualize comparison of simulations. The methodology followed was similar in some ways to the simulation overlaps. The genetic conditions are represented using the same symbols, but the colours of the edges follow a different strategy.
 
 
Each simulation will have a colour by default, for instance, simulation 1 will have the colour green, and simulation 2 will have the colour red.
 
 
According to the amount of flux of each simulation the colours will vary. If the amount of flux is bigger in simulation 1 then the colours will vary in a gradient that spans from green to black (where black means that there is no difference in fluxes):

If the flux value in simulation 2 is greater, the colours will vary from red to black:

This will allow the user to identify where flux paths differ in the simulations (pure colours) and where both share fluxes (darker colours). At the same time, there can be reactions that are reversible and the fluxes of the compared simulations take different directions, in this case the edges will have the colour of the simulation that follows the direction they are pointing, also giving the user an easy way to understand where the simulations differ:

The thickness of the edges is calculated using the mean of the flux values of both simulations. On top of this some filters are also generated, where it is possible to hide zero value fluxes according to the simulation the user wants to see.
 
 
The labels keep the information of the fluxes from both simulations. RF stands for Reference Flux distribution and TF for Target Flux Distribution.
