TCGA cancer genome CNA data

[zhan...@gmail.com]

Hi, I am trying to find out how TCGA calculates the average CNA per tumor sample. How is homo and hetero loss treated compared to gains? I am aware of the way of dealing with single regions, for which CNA ranges from -2 to +2. Does anyone know a source of literature about this?
