# ilr-phylogenetic: Isometric Log-ratio Transform applied to a phylogenetic tree¶

#### Docstring:

Usage: qiime gneiss ilr-phylogenetic [OPTIONS]

Calculate balances given a rooted phylogeny.

Inputs:
--i-table ARTIFACT FeatureTable[Frequency | Composition]
The feature table containing the samples in which
the ilr transform will be performed.      [required]
--i-tree ARTIFACT       A rooted phylogeny of feature identifiers that
Phylogeny[Rooted]     defines the partitions of features.  Each tip in the
hierarchycorresponds to the feature identifiers in
the table. This tree can contain tip ids that are
not present in the table, but all feature ids in the
table must be present in this tree.  This assumes
that all of the internal nodes in the tree have
labels. This tree may contain polytomic nodes (i.e.,
nodes with more than two children), in which case
they will be bifurcated.                  [required]
Parameters:
--p-pseudocount NUMBER  The value to add to zero counts in the feature
table.                                [default: 0.5]
Outputs:
--o-balances ARTIFACT FeatureTable[Balance]
The resulting balances from the ilr transform.
[required]
--o-hierarchy ARTIFACT  Hierarchy from bifurcated phylogeny
Hierarchy                                                       [required]
Miscellaneous:
--output-dir PATH       Output unspecified results to a directory
--verbose / --quiet     Display verbose output to stdout and/or stderr
during execution of this action. Or silence output
if execution is successful (silence is golden).
--examples              Show usage examples and exit.
--citations             Show citations and exit.
--help                  Show this message and exit.

Isometric Log-ratio Transform applied to a phylogenetic tree

Calculate balances given a rooted phylogeny.

Parameters
----------
table : FeatureTable[Frequency | Composition]
The feature table containing the samples in which the ilr transform
will be performed.
tree : Phylogeny[Rooted]
A rooted phylogeny of feature identifiers that defines the partitions
of features.  Each tip in the hierarchycorresponds to the feature
identifiers in the table. This tree can contain tip ids that are not
present in the table, but all feature ids in the table must be present
in this tree.  This assumes that all of the internal nodes in the tree
have labels. This tree may contain polytomic nodes (i.e., nodes with
more than two children), in which case they will be bifurcated.
pseudocount : Float, optional
The value to add to zero counts in the feature table.

Returns
-------
balances : FeatureTable[Balance]
The resulting balances from the ilr transform.
hierarchy : Hierarchy
Hierarchy from bifurcated phylogeny
