The simple network is constituted of seven reactions. The reactions: Disered, Biomass and substrate represents the production of the chemical of interest, the formation of biomass and the uptake of metabolite M1 from surrounding media, respectively.

The coefficient of reaction <b>R2</b> (M1->M3) are such that two molecules of M1 create one molecule of M3, while the stoichiometric coefficients of all other reactions reflect a one-to-one relationship between molecule quantities.


=Brief tutorial=

This brief tutorial will help you to begin working with OptKnock4OptFlux.

*To start, you will need load a model in OptFlux(see how to [[How_to_create_a_new_model | here]]). You must be attention to select a correct biomass flux.

==Run OptKnock==

* 1 - Start by accessing the menu '''Plugins->OptKnock->OptKnock Optimization'''.

<br>
<br>

* 2 - The following dialog will be displayed.

<br>
<b>1. <i>Select Project and Model</i></b>

You can select the model/project to work.

<br>
<b>2. <i>Substrate Definition</i></b>

You can select the substrate flux and its uptake value.

<br>
<b>3. <i>Biomass Minimum Value</i></b>

You can define the minimum value for the biomass (in %).

<br>
<b>4. <i>Desired Flux Definition</i></b>

You can select the reaction representing the production of the desired compound.

<br>
<b>5. <i>Knockouts Definition</i></b>

You can define de maximum numbers of knockouts.

<br>
<b>6. <i>Selected Environmental Conditions</i></b>

You can define the environmental conditions if you have created any.

<br>
<br>

* 3 - After execution, a new datatype will be placed in the clipboard, under the '''Optimizations Results -> OptKnock Optimizations'''.
