Input ChIP-seq data (counts), which approximately follow Poisson Distribution. |
Please note the input data can be a single value, a vector or a matrix. If it is a matrix, the default format is N row by M column. Each row represents for one gene, and each column represents for one bin.
After VST transformation, the return data matrix would follow Normal Distribution with a constant variance 1
