_multi_deletion
(model, entity, element_lists, method="fba", solution=None, processes=None, **kwargs)[source]¶ Provide a common interface for single or multiple knockouts.
Parameters: - model (cobra.Model) – The metabolic model to perform deletions in.
- entity ('gene' or 'reaction') – The entity to knockout (
cobra.Gene
orcobra.Reaction
). - element_lists (list) – List of iterables ``cobra.Reaction``s or ``cobra.Gene``s (or their IDs) to be deleted.
- method ({"fba", "moma", "linear moma", "room", "linear room"}, optional) – Method used to predict the growth rate.
- solution (cobra.Solution, optional) – A previous solution to use as a reference for (linear) MOMA or ROOM.
- processes (int, optional) – The number of parallel processes to run. Can speed up the computations if the number of knockouts to perform is large. If not passed, will be set to the number of CPUs found.
- kwargs – Passed on to underlying simulation functions.
Returns: A representation of all combinations of entity deletions. The columns are ‘growth’ and ‘status’, where
- index : frozenset([str])
The gene or reaction identifiers that were knocked out.
- growth : float
The growth rate of the adjusted model.
- status : str
The solution’s status.
Return type: pandas.DataFrame

single_reaction_deletion
(model, reaction_list=None, method="fba", solution=None, processes=None, **kwargs)[source]¶ Knock out each reaction from a given list.
Parameters: - model (cobra.Model) – The metabolic model to perform deletions in.
- reaction_list (iterable, optional) – ``cobra.Reaction``s to be deleted. If not passed, all the reactions from the model are used.
- method ({"fba", "moma", "linear moma", "room", "linear room"}, optional) – Method used to predict the growth rate.
- solution (cobra.Solution, optional) – A previous solution to use as a reference for (linear) MOMA or ROOM.
- processes (int, optional) – The number of parallel processes to run. Can speed up the computations if the number of knockouts to perform is large. If not passed, will be set to the number of CPUs found.
- kwargs – Keyword arguments are passed on to underlying simulation functions
such as
add_room
.
Returns: A representation of all single reaction deletions. The columns are ‘growth’ and ‘status’, where
- index : frozenset([str])
The reaction identifier that was knocked out.
- growth : float
The growth rate of the adjusted model.
- status : str
The solution’s status.
Return type: pandas.DataFrame

double_reaction_deletion
(model, reaction_list1=None, reaction_list2=None, method="fba", solution=None, processes=None, **kwargs)[source]¶ Knock out each reaction pair from the combinations of two given lists.
We say ‘pair’ here but the order order does not matter.

- solution (cobra.Solution, optional) – A previous solution to use as a reference for (linear) MOMA or ROOM.
- processes (int, optional) – The number of parallel processes to run. Can speed up the computations if the number of knockouts to perform is large. If not passed, will be set to the number of CPUs found.
