K-means classification for all the expressed probes across eighteen (18) autologous, paired eutopic and ectopic endometrial samples. The groups of genes showing similar expression pattern across the samples are clustered in four clusters (K1-K4) (A). Cluster K1 contains 3938 probes (3210 genes), cluster K2 contains 14901 probes (8194 genes), cluster K3 contains 6982 probes (6078 genes) and cluster K4 contains 9825 probes (8505 genes). The right panel (B) shows the average expression patterns of co-expressed probes each cluster across the annotated groups.
