Adds a 'SPIKE'-in to the observations set at different thresholds of loss/gain to aid in tracking the effect of infercnv operations and for defining the final scaling.
spike_in_variation_chrs(infercnv_obj, spike_in_chrs = NULL,
spike_in_multiplier_vec = c(0.01, 2), max_cells = 100,
min_genes_per_chr = 100)An infercnv object populated with raw count data
: define the chromsomes that will serve as signal for gain/loss default: picks chrosomes in order of size
: factors that define relative expression for gain/loss and must match ordering of spike_in_chrs above default: c(0.01, 2.0)
max number of cells to incorporate in the spike-in
: default 100
