scDengue: Dengue infected macrophages; gene expression data from GEO...

In lubianat/FCBF: Fast Correlation Based Filter for Feature Selection

Description

Expression data from single cells, from adengue virus infection study by Zanini et al, #' 2018. The expression was filtered to get cells 12 hours after infection with #' a multiplicity of infection (moi) of 1 (dengue) or uninfected(ctrl). Gene counts were normalized via Bioconductor package "SCNorm".

Usage

data(scDengue)

Format

An object of class SingleCellExperiment

Details

Gene expression has to be discretized for use in FCBF.

Source

exprs <- SummarizedExperiment::assay(scDengue, 'logcounts')
infection <- SummarizedExperiment::colData(scDengue)
target <- infection$infection
# Discretize gene expression
