Strategies used by Genome Strip to detect CNVs

Dear all,

I'm only want to know which strategies are used by Genome Strip in order to detect the CNVs... I looking for in the Genome Strip web page but I'm not sure... I saw in different papers where they classify the detection using the Discordant Reads (RP), Read depth(RD). Another papers also include Split reads (SR) signals or even local assembly (AS).

So I will appreciate if you could clarify me which strategies used this tool...

Thanks for your help
