Sentence examples for by the quantile normalization from inspiring English sources

The raw data from microarray were pre-processed through three steps: background correction was performed, the data were then log-transformed to log2 scale, and normalized by the quantile normalization method implemented in the Genome Studio software (Illumina Inc.).

Log2 transformation of the expression value was performed for each probe, and the data was normalized by the quantile normalization method.

Raw probe intensities for all treatment conditions were normalized by the quantile normalization algorithm [ 29] using GenomeStudio software from Illumina and log-2 transformed expression obtained for analyses.

Another algorithm to carry out the quantile normalization was introduced by Amaratunga and Cabrera [ 22].

The mouse data are part of a study of AHR-/ animals described elsewhere [ 28], but were pre-processed separately for this study to avoid introducing bias by including AHR-/ mice in the quantile-normalization step of pre-processing.
