Sorry, found the normalized count of each gene should be calculated with the formula:
norm_counts.table <- t(t(d$pseudo.alt)*(d$samples$norm.factors)) instead of: (d$pseudo.alt)*(d$samples$norm.factors). The formula colSums(d$pseudo.alt)*d$samples$norm.factors is used to compare the total counts of each library only, not the individual genes.
