[BioC] TMM Normalization without replicate

[Jieon Lee [guest]]

Hi, I am a graduate student at POSTECH and I ran into some troubles while running edgeR program. 
Currently I have six Chip-Seq samples, all of different condition. There are no biological replicate and no control sample. 
So when I try to run edgeR, it does not run for there is no biological replicate used for statistical testing. 

I wonder if there is a way to export TMM normalized count from edgeR package without compliting the program. 
I know the program should run up till calcNormFactor and give normfactor but without biological replicate, it cannot calculate dispersion and the whole program fails to run. 
Is there a way to export just the TMM normalized data without doing statistical testing? 
If so, what are the codes that allow such methods? 

I tried cpm function but cpm may use raw or normalized data not gives a normalized data from raw data.

Thanks in advance,
