Multidimensional scaling plot of reads counts per library. Barycenters are plotted in red for the ECB and in blue for ABB. The samples on maize are represented by squares and those on mugwort by circles. a and b plots present all replicates after filtering and normalization in ABB-ref and ECB-ref, respectively. c present replicates in ECB-ref without one outlier replicate (ECB-mug2)
