Reference material for distinguishing focal CNV and chromosome CNV

Question

[CY]

We are developing a method that can accurately distinguish focal and chromosome CNV (amplification). To validate our method, we need some reference materials that contain either focal or chromosome CNV. Does anyone know where can we purchase such reference materials?

first of all I would not do this because there are thousands of such tools, second - why do you need to develop a tool if you don't have data to work with? 0.o
