CatFun takes the results of DESeq2 (Love et al. 2014) and of TaFuR FunkyTax to categorize functions as conserved, equivalent, divergent, or enhanced following Phillips et al. (submitted). These categories describe how differences in metagenome functional repetoire between two or more factor levels relate to differences in underlying microbiome community structure.
1 | CatFun(tf, ds, alpha = 0.05)
|
tf |
Output of TaFuR, which is a list of length five. |
ds |
Results of DESeq2::results. |
alpha |
P-value threshold to be applied to Benjamini-Hochberg (Benjamini and Hochberg 1956) adjusted p-values for both DESeq2 and TAFuR analysis. This threshold determines boundaries for function classification. |
Output is a list of two with the following:
1: |
ggplot object summarizing classification. |
2: |
Data frame with each function rank-ordered according to abundance and with functional classifications provided. |
