 I have following output of DESeq2 on the following functions. It seems that if changes the fitType for dispersion only when I compute variance stabilized values. Why doesn't it change the dispersion fitType when the function DESeq is called?

dds.1 = DESeqDataSetFromMatrix(countData=signal, colData=Design, design=~condition)
> dds <- DESeq(dds.1)
estimating size factors
estimating dispersions
gene-wise dispersion estimates

-- note: fitType='parametric', but the dispersion trend was not well captured by the
   function: y = a/x + b, and a local regression fit was automatically substituted.
   specify fitType='local' or 'mean' to avoid this message next time.
