Dr Steve Lianoglou,

Thanks for your reply.

The sample size is too small as you mentioned.
That matter may be left out of consideration because the actuall sample size is over 2000x300.

I read the tutorial of limma and the source code of "normalizeBetweenArrays", however, I  couldn't understand how NA values were processed.
Could you show me the prodess?

Thanks,
