This works for models which follow the standard convention for constructing and naming these reactions. The reaction should only contain the single metabolite being exchanged, and the id should be EX_ or DM_ . :param model: The model whose demand and exchange reactions need to be annotated. :type model: cobra.Model .. py:function:: delete_model_genes(model: cobra.Model, gene_list: Union[List[cobra.Gene], Set[cobra.Gene], List[str], Set[str]], cumulative_deletions: bool = True, disable_orphans: bool = False) -> None Temporarily remove the effect of genes in `gene_list`. It sets the bounds to "zero" for reactions catalysed by the genes in `gene_list` if deleting the genes stops the reactions from proceeding. :param model: The model whose reaction bounds are to be set. :type model: cobra.Model :param gene_list: The list of genes to knock-out. :type gene_list: list of cobra.Gene :param cumulative_deletions: If True, then any previous deletions will be maintained in the model (default True). Unused, ignored. :type cumulative_deletions: bool, optional :param disable_orphans: If True, then orphan reactions will be disabled. Currently, this is not implemented (default False). Unused, ignored. :type disable_orphans: bool, optional :param .. deprecated :: 0.25: Use cobra.manipulation.knock_out_model_genes to simulate knockouts and cobra.manipulation.remove_genes to remove genes from the model. .. seealso:: :obj:`knock_out_model_genes`, :obj:`remove_model_genes` .. py:function:: knock_out_model_genes(model: cobra.Model, gene_list: Iterable[Union[cobra.Gene, int, str]]) -> List[cobra.Reaction] Disable the genes in `gene_list`. It sets the bounds to "zero" for reactions catalysed by the genes in `gene_list` if deleting the genes would stop the reactions from proceeding. The changes are reverted upon exit if executed within the model as context. :param model: The model whose reaction bounds are to be set. :type model: cobra.Model :param gene_list: The list of genes to knock-out. :type gene_list: list of cobra.Gene :returns: A list of cobra.Reactions that had the bounds turned to zero. :rtype: list[cobra.Reaction] .. py:function:: prune_unused_metabolites(model: cobra.Model) -> Tuple[cobra.Model, List[cobra.Metabolite]] Remove metabolites not involved in any reactions. :param model: The model to remove unused metabolites from. :type model: cobra.Model :returns: * *cobra.Model* -- Input model with unused metabolites removed. * *list of cobra.Metabolite* -- List of metabolites that were removed. .. py:function:: prune_unused_reactions(model: cobra.Model) -> Tuple[cobra.Model, List[cobra.Reaction]] Remove reactions with no assigned metabolites, returns pruned model. :param model: The model to remove unused reactions from. :type model: cobra.Model :returns: * *cobra.Model* -- Input model with unused reactions removed. * *list of cobra.Reaction* -- List of reactions that were removed. .. py:function:: remove_genes(model: cobra.Model, gene_list: Union[List[cobra.Gene], Set[cobra.Gene], List[str], Union[str]], remove_reactions: bool = True) -> None Remove genes entirely from the model. This will also simplify all gene-reaction rules with the genes inactivated. :param model: The model to remove genes from. :type model: cobra.Model :param gene_list: The list of gene objects to remove. :type gene_list: list of cobra.Gene or gene ids :param remove_reactions: Whether to remove reactions associated with genes in `gene_list` (default True). :type remove_reactions: bool, optional .. py:function:: escape_ID(model: cobra.Model) -> None Make all model component object IDs SBML compliant. :param model: The model to operate on. :type model: cobra.Model .. py:function:: rename_genes(model: cobra.Model, rename_dict: Dict[str, str]) -> None Rename genes in a model from the `rename_dict`. :param model: The model to operate on. :type model: cobra.Model :param rename_dict: The dictionary having keys as old gene names and value as new gene names. :type rename_dict: dict of {str: str} .. py:function:: check_mass_balance(model: cobra.Model) -> Dict[cobra.Reaction, Dict[cobra.Metabolite, float]] Check mass balance for reactions of `model` and return unbalanced ones. :param model: The model to perform check on. :type model: cobra.Model :returns: **dict of {cobra.Reaction** -- Returns an empty dict if all components are balanced. :rtype: dict of {cobra.Metabolite: float}} .. py:function:: check_metabolite_compartment_formula(model: cobra.Model) -> List[str] Check metabolite formulae of `model`. :param model: The model to perform check on. :type model: cobra.Model :returns: Returns an empty list if no errors are found. :rtype: list of str
