Sentence examples for feature of the array from inspiring English sources

Arrays were scanned on a GeneChip Scanner 3000, and fluorescence intensity for each feature of the array was obtained by using GeneChip Operating Software (Affymetrix).

An important feature of the array analysis is a computational pipeline that determines SNP allele ratios based upon chromosome copy number.

Finally, an additional valuable feature of the array technology is its ability to identify PVL genes, since these genes coding for a cytotoxin are claimed to be a major threat in severe tissue necrosis (17– 217.

Further improvement of the technology led to an increased number of features on the array and use of shorter sequences as targets most frequently oligonucleotides.

For 2,237 unigenes, the number of features on the array allowed the design of two different probes for the same contig, while for the remaining 39,326 unigenes only one probe was designed.

In addition, since the number of features on the array allowed for more than the number of predicted transcripts, two different probes were designed for each transcript if possible.

Microarray experiments are often limited in power by the small number of samples used to derive a panel of prognostic genes relative to the large number of features on the array.

(iv) The Array Design Format (ADF) tab-delimited file describes the design of an array, i. e. the sequence located at each feature on the array and annotation of the sequences.

Most of these metrics (interquartile density, signal range, uniformity mean, uniformity CV (coefficient of variation), number of empty features on the array, mean empty, the number of random control features present on the array, mean Random) assume probe randomization on the array surface.

The density of features on the array varies between platforms, from 20 000 spots per slide for a typical spotted array, to several million for platforms such as NimbleGen and Affymetrix that use in situ synthesized oligos.

For the majority of features on the array (12,331; 70.1%), only a single QTL was detected while for 2,503 features (29.9%), two or more QTLs were found for both tissues combined (Table 1a).
