rmreactant (reaction) - Remove species object from reaction object reactants

Syntax

rmreactant(reactionObj, SpeciesName) rmreactant(reactionObj, speciesObj)

Arguments

`reactionObj`	Reaction object.
`SpeciesName`	Name for a species object. Enter a species name or a cell array of species names.
`speciesObj`	Species object. Enter a species object or an array of species objects.

Description

rmreactant(reactionObj, SpeciesName), in a reaction object (reactionObj), removes a species object with a specified name (SpeciesName) from the property Reactants, removes the species name from the property Reaction, and updates the property Stoichiometry to exclude the species coefficient.

rmreactant(reactionObj, speciesObj) removes a species object as described above using a MATLAB variable for a species object, or a model index for a species object.

The species object is not removed from the parent model property Species. If the species object is no longer used by any reaction, you can use the method delete to remove it from the parent object.

If one of the species specified does not exist as a reactant, a warning is returned.

Examples

Example 1

This example shows how to remove a reactant that was added to a reaction by mistake. You can remove the species object using the species name.

modelObj = sbiomodel('cell');
reactionObj = addreaction(modelObj, 'Phosphocreatine + ADP + Pi -> creatine + ATP');
rmreactant(reactionObj, 'Pi')

Example 2

Remove a species object using a model index to a species object.

modelObj = sbiomodel('cell');
reactionObj = addreaction(modelObj, 'A -> B + C');

reactionObj.Reaction    
ans =
    A + B -> C

rmreactant(reactionObj, modelObj.Species(1));
reactionObj.Reaction   
 
ans =
    A -> C
