| Description |
Retro_RF10
|
| Data processing |
In each sample, intensity values for both channels (Cy5 and Cy3) were independently transformed using a quantile equalization method, yielding pairs of normalized values of non-exponential scale. We enforced the normalized values to follow an independent hypothetical standard normal distribution, keeping only the rank within a sample and a chennel. The abundance of transcription for each probe was then defined by subtracting the value of Cy5 from that of Cy3, which are free from dye-sensor bias and can be treated just like the log ratio of Cy5 and Cy3.
