pre_value |
Each gene's measured intensity was divided by its control channel value in each sample. When the control channel value was below 10.0 the data point was considered bad. The 50th percentile of all measurements was used as a positive control for each sample. Each measurement for each gene was divided by this synthetic positive control, assuming that this was at least 0.01. The bottom tenth percentile was used as a test for correct background subtraction. |
