Identify duplicate reactions globally by checking if any
two reactions have the same metabolites, same directionality and are in
the same compartment.
This can be useful to curate merged models or to clean-up bulk model
modifications. The heuristic compares reactions in a pairwise manner.
For each reaction, the metabolite annotations are checked for a description
of the structure (via InChI and InChIKey).If they exist, substrates and
products as well as the stoichiometries of any reaction pair are compared.
Only reactions where the substrates, products, stoichiometry and
reversibility are identical are considered to be duplicates.
This test will not be able to identify duplicate reactions if there are no
structure annotations. Further, it will report reactions with
differing bounds as equal if they otherwise match the above conditions.

Parameters
----------
title : str
A human-readable descriptive title of the test case.
format_type : str
A string that determines how the result data is formatted in the
report. It is expected not to be None.
* 'number' : 'data' is a single number which can be an integer or
float and should be represented as such.
* 'count' : 'data' is a list, set or tuple. Choosing 'count' will
display the length of that list e.g. number of metabolites without
formula.
* 'percent' : Instead of 'data' the content of 'metric' ought to be
displayed e.g. percentage of metabolites without charge.
'metric' is expected to be a floating point number.
* 'raw' : 'data' is ought to be displayed "as is" without formatting.
This option is appropriate for single strings or a boolean output.
message : str
A short written explanation that states and possibly explains the test
result.
data
Raw data which the test case generates and assesses. Can be of the
following types: list, set, tuple, string, float, integer, and boolean.
metric: float
A value x in the range of 0 <= x <= 1 which represents the fraction of
'data' to the total in the model. For example, if 'data' are all
metabolites without formula, 'metric' should be the fraction of
metabolites without formula from the total of metabolites in the model.
Returns
-------
function
The decorated function, now extended by the attribute 'annotation'.
Notes
-----
Adds "annotation" attribute to the function object, which stores values for
predefined keys as a dictionary. | 3.388693 | 3.617796 | 0.936673 |

return int((sigma >= tol).sum()) | def rank(matrix, atol=1e-13, rtol=0) | Estimate the rank, i.e., the dimension of the column space, of a matrix.
The algorithm used by this function is based on the singular value
decomposition of `stoichiometry_matrix`.
Parameters
----------
matrix : ndarray
The matrix should be at most 2-D. A 1-D array with length k
will be treated as a 2-D with shape (1, k)
atol : float
The absolute tolerance for a zero singular value. Singular values
smaller than ``atol`` are considered to be zero.
rtol : float
The relative tolerance for a zero singular value. Singular values less
than the relative tolerance times the largest singular value are
considered to be zero.
Notes
-----
If both `atol` and `rtol` are positive, the combined tolerance is the
maximum of the two; that is::
tol = max(atol, rtol * smax)
Singular values smaller than ``tol`` are considered to be zero.
Returns
-------
int
The estimated rank of the matrix.

provide the option of the absolute tolerance. | 3.581346 | 3.917831 | 0.914114 |

return vh[num_nonzero:].conj().T | Compute an approximate basis for the null space (kernel) of a matrix.
The algorithm used by this function is based on the singular value
decomposition of the given matrix.
Parameters
----------
matrix : ndarray
The matrix should be at most 2-D. A 1-D array with length k
will be treated as a 2-D with shape (1, k)
atol : float
The absolute tolerance for a zero singular value. Singular values
smaller than ``atol`` are considered to be zero.
rtol : float
The relative tolerance for a zero singular value. Singular values less
than the relative tolerance times the largest singular value are
considered to be zero.
Notes
-----
If both `atol` and `rtol` are positive, the combined tolerance is the
maximum of the two; that is::
tol = max(atol, rtol * smax)
Singular values smaller than ``tol`` are considered to be zero.
Returns
-------
ndarray
If ``matrix`` is an array with shape (m, k), then the returned
nullspace will be an array with shape ``(k, n)``, where n is the
estimated dimension of the nullspace.

each focusing on a different macromolecular component for instance
a (1 gDW ash) + b (1 gDW phospholipids) + c (free fatty acids)+
d (1 gDW carbs) + e (1 gDW protein) + f (1 gDW RNA) + g (1 gDW DNA) +
h (vitamins/cofactors) + xATP + xH2O-> 1 gDCW biomass + xADP + xH + xPi.
This function aims to identify if the given biomass reaction 'reaction',
is a lumped all-in-one reaction, or whether it is just the final
composing reaction of all macromolecular components. It is important to
identify which other reaction belong to a given biomass reaction to be
able to identify universal biomass components or calculate detailed
precursor stoichiometries.
Parameters
----------
model : cobra.Model
The metabolic model under investigation.
reaction : cobra.core.reaction.Reaction
The biomass reaction of the model under investigation.
Returns
-------
list
One or more reactions that qualify as THE biomass equation together.
Notes
-----
Counting H2O, ADP, Pi, H, and ATP, the amount of metabolites in a split
reaction is comparatively low:
Any reaction with less or equal to 15 metabolites can
probably be counted as a split reaction containing Ash, Phospholipids,
Fatty Acids, Carbohydrates (i.e. cell wall components), Protein, RNA,
DNA, Cofactors and Vitamins, and Small Molecules. Any reaction with more
than or equal to 28 metabolites, however, (21 AA + 3 Nucleotides (4-ATP)
+ 4 Deoxy-Nucleotides) can be considered a lumped reaction.
Anything in between will be treated conservatively as a lumped reaction.
For split reactions, after removing any of the metabolites associated with
growth-associated energy expenditure (H2O, ADP, Pi, H, and ATP), the
only remaining metabolites should be generalized macromolecule precursors
e.g. Protein, Phospholipids etc. Each of these have their own composing
reactions. Hence we include the reactions of these metabolites in the
set that ultimately makes up the returned list of reactions that together
make up the biomass equation. | 3.768749 | 3.740791 | 1.007474 |

Return a list of essential precursors missing from the biomass reaction.
There are universal components of life that make up the biomass of all
known organisms. These include all proteinogenic amino acids, deoxy- and
ribonucleotides, water and a range of metabolic cofactors.
Parameters
----------
model : cobra.Model
The metabolic model under investigation.
reaction : cobra.core.reaction.Reaction
The biomass reaction of the model under investigation.
Returns
-------
list
IDs of essential metabolites missing from the biomass reaction. The
IDS will appear in the models namespace if the metabolite exists, but
will be using the MetaNetX namespace if the metabolite does not exist
in the model.
Notes
-----
"Answering the question of what to include in the core of a biomass
objective function is not always straightforward. One example is different
nucleotide forms, which, although inter-convertible, are essential for
cellular chemistry. We propose here that all essential and irreplaceable
molecules for metabolism should be included in the biomass functions of
genome scale metabolic models. In the special case of cofactors, when two
forms of the same cofactor take part in the same reactions (such as NAD
and NADH), only one form could be included for the sake of simplicity.
When a class of cofactors includes active and non-active interconvertible
forms, the active forms should be preferred. [1]_."
Please note, that [1]_ also suggest to count C1 carriers
(derivatives of tetrahydrofolate(B9) or tetrahydromethanopterin) as
universal cofactors. We have omitted these from this check because there
are many individual compounds that classify as C1 carriers, and it is not
clear a priori which one should be preferred. In a future update, we may
consider identifying these using a chemical ontology.
