scDengue {FCBF} | R Documentation |
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".
data(scDengue)
An object of class SingleCellExperiment
Gene expression has to be discretized for use in FCBF.
