Fig. 1

Correlation between samples of benchmark dataset. The figure presents the results of a multidimensional scaling of the covariance matrix of the read count data for the 861 investigated samples onto a two-dimensional plane. The colors depict samples from other sequencing centres (BCM - Baylor College of Medicine, BGI - Bejing Genomics Institute, BI - The Broad Institute, ILLUMINA - Illumina, MPIMG - The Max Planck Institute of Molecular Genetics, SC - The Welcome Trust Sanger Institute, WUGSC - Washington University Genome Science Center). It is worth noticing that samples are grouped into several clusters, mainly according to the research center where they were sequenced. However, samples sequenced in the same research center are also divided into subgroups, e.g. cyan dots, which depict the samples from Baylor College of Medicine. The figure was prepared by R’s cmdscale function
