Package: fCI 1.43.0

fCI: f-divergence Cutoff Index for Differential Expression Analysis in Transcriptomics and Proteomics

(f-divergence Cutoff Index), is to find DEGs in the transcriptomic & proteomic data, and identify DEGs by computing the difference between the distribution of fold-changes for the control-control and remaining (non-differential) case-control gene expression ratio data. fCI provides several advantages compared to existing methods.
