The goal of this package is to provide functions for advanced analysis of microbial flow cytometry data. One of the applications is the derivation of phenotypic diversity estimates, such as depicted below (data available at doi:10.5061/dryad.m1c04), which can be compared with 16S rRNA gene amplicon data sets.
- Tutorial can be found here.

| Functions | Actions |
|---|---|
| flowBasis | Function part of the flowFDA package (in development) which performes bivariate kernel density estimations on the phenotypic parameters |
| Diversity | Calculation of Hill diversities of order 0, 1 and 2 from fingerprint object |
| Diversity_rf | More accurate (i.e., smaller errors) calculation of Hill diversities from flowSet. It is slower than Diversity(). |
| Diversity_16S | Calculation of Hill diversities from 16S amplicon data for comparison with Diversity(). |
| Evenness | Calculation of pareto evenness (Wittebolle L. et al. (2009)) from fingerprint object (1 = maximum evenness, 0 = minimum evenness) |
| So | Calculation of Structural Organization parameter (Koch et al. (2014), Frontiers in Microbiology) |
| CV | Calculation of Coefficient of Variation (CV) of the fingerprint object |
| beta_diversity_fcm | Non-metric Multidimensional Scaling (NMDS) or PCoA of the phenotypic fingerprints |
| time_discretization | Function for subsetting .fcs files in time intervals and exporting them as new .fcs files. Designed for the analysis of on-line experiments. |
| FCS_resample | Resamples sample files from flowSet object to an equal number of cells. Standard is to the minimum sample size. |
| FCS_clean | Denoises all samples by means of automated identification and removal of fluorescence anomalies in flow cytometry data |
| Functions | Actions |
|---|---|
| flowRate | Calculation of growth rates of microbial populations from flow cytometry data. |
