Log2 copy ratio
WitrynaSo for one of your values: log2 cn: 0.4194 This is the ratio between tumor and normal (or between your cell line and a panel of "normal" cells) To convert to absolute copy number, we do (2^0.4194)*2 = 2.674742 The multiplication by two is because we assume a diploid genome in the normal.
