This function removes genes that are lowly expressed.
The droplets are split into the test set and debris set, and the Counts
Per Million mapped reads (CPM) are calculated for each. Then, only genes
that have a CPM of at least cpm_thresh
in both the test set and
debris set are kept.
filter_genes(x, cpm_thresh = 10, verbose = FALSE)
