Apply ANCOM to identify features that differ in abundance.

Apply Analysis of Composition of Microbiomes (ANCOM) to identify features that are differentially abundant across groups.

Parameters

metadata : MetadataColumn[Categorical]: The categorical sample metadata column to test for differential abundance across.
transform_function : Str % Choices('sqrt', 'log', 'clr'), optional: The method applied to transform feature values before generating volcano plots.
difference_function : Str % Choices('mean_difference', 'f_statistic'), optional: The method applied to visualize fold difference in feature abundances across groups for volcano plots.
