Additional file 2: Figure S2. of Next-generation sequencing for virus detection: covering all the bases

Average depth of viroid 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 Hop stunt viroid (A and C) and Citrus dwarfing viroid (B and D).
