Average depth of virus genome coverage obtained through read-mapping. Heat maps displaying the average depth of coverage of each nucleotide along the virus genome (X-axis), obtained through read-mapping (1000 replications) of different subset-sizes of small (sRNA) (a and b) and poly(A)-selected (c) or ribo-depleted RNA (d) reads onto the reference genomes of Grapevine leafroll-associated virus 3 (GLRaV-3) (a and c) and Citrus tristeza virus (CTV) (b and d). The start of the coat protein subgenomic RNA is indicated with an arrow
