All spots on the microarray were divided into 16 categories as shown Table 5 after assigning "1" for expressed genes and "0" for unexpressed genes.
The genes present on the microarray were divided into two groups according to whether the PCR amplified transcripts (S') or the T7 amplified transcripts (M') were more abundant.
Essentially, all microarrays were normalized to the median value of the control samples such that each measurement for each probe, in each microarray, was divided by the median of that probe's measurement in the corresponding control samples.
To correlate retroviral integration and gene activity, average expression values from the three microarrays were divided into four classes, i.e., absent, low (below the 25th percentile in a normalized distribution), intermediate (between the 25th and the 75th percentile) and high (above the 75th percentile).
The CustomArray™ 4x2k is a microarray that is divided into 4 sectors, each of which can contain up to 2,240 different oligonucleotide probes (spots) and can be hybridized individually with different targets using a provided sectored hybridization cap.
In brief, a sub-experiment essentially consists of a collection of microarrays that is divided into two sample categories, or phenotypes.
First, the microarray matrix G ∈ ℝ m × n is divided into two submatrices: a complete matrix G 1 ∈ ℝ m 1 × n consisting of genes without missing values and an incomplete matrix G 2 ∈ ℝ (m - m 1 ) × n consisting of genes with missing values.
FunnyBase (Fig. 1) is divided into 3 modules: Sequence Pipeline, Hierarchical Annotation, and Microarray Production and Analysis.
BBGD is divided into two separate but related entities, a sequence database and a microarray database.
