Sentence examples for intensity array from inspiring English sources

Raw intensity array data were normalized within and across samples using Illumina's BeadStudio software v.3.3.7.

Data files (cel) and corresponding text files were uploaded into the dCHIP program and normalized to the median intensity array.

Array data were normalized against the median intensity array for each experiment using the invariant set normalization method [ 33].

A total of 3,321 and 3,828 combinations were considered for ratio and single intensity array data, respectively (see Methods).

Indeed, several sources of variation like degree of differential expression, spot intensity, array averaging and filtering, probe design, binding sites and variances in amplification methodologies prevent a direct validation of microarray results by qPCR.

The increase in dimension is achieved by different techniques such as multitag fluorescence imaging, Matrix Assisted Laser Desorption / Ionization (MALDI) imaging or Raman imaging, which record for each pixel an N-dimensional intensity array, representing local abundances of molecules, residues or interaction patterns.

To ensure that all arrays used for expression profiling had similar scale factors, and thus similar overall intensity, arrays with factors below percentile 7.5 and above percentile 92.5 were removed from analyses.

A similar trend of higher correlations among up-regulated genes was observed by Beckman et al. (%R[14}%), who proposed that this effect may be due to the increased variability observed in low-intensity array spots, i.e. down-regulated genes. However, in the current study, no trend was apparent in the effects of average array spot intensity on correlation of data (Fig. 1b).

To scale between arrays, the global median intensity per array was set at 1000.

To control for chip-wide variations in intensity, each array was normalized to the 50th percentile of genes.

Although this normalization minimizes within-array spatial biases, there is still a difference in overall signal intensity between arrays, which makes it difficult to compare them.
