(A) FASTQC quality check report on the read length distribution of miRNA-Seq data after adaptor and quality-based trimming of reads. (B) Heatmap plot and dendogram based on sample-to-sample Euclidean distances between miRNA-Seq samples (dark for small distances). MDCK 1–4 represent the biological replicates of MDCK cells, MDCK-Ras 1–4 those of MDCK-Ras cells. (PDF 253 kb
