Hi, ALL, I want to do unsupervised clustering using segmented copy number variation data (like those derived from SNP array), and then visualize it. The results will look like the following figure (Figure 1A). Samples are clustered based on their CNV.
I know how to draw a heatmap with clustering using data in matrix in R software. However, the data structure of the segmented copy number is quite different. I only know IGV tools can visualize this kind of data. But IGV doesn't provide options to do the clustering. Can anybody give me some instructions to do this? Any help will be greatly appreciated.
