Using dose/response modeling with pre-normalized data

I am using ExpressAnalyst to analyze some dose-response data. I would like to use pre-normalized data in log2CMP format that has been pre-selected for genes that are differentially expressed. I am able to remove all of the filters during normalization except the low abundance method. Since my data is log transformed many of the genes are marked as low abundance. Will this effect the downstream dose-response analysis? If so how can I remove this low abundance averaging?

It is not clear to me why you cannot turn off the low-abundace filter (i.e., you can set the filter to 0 - see below)? Please follow our post guideline
