Sentence examples for batch effects such as from inspiring English sources

Although lumi normalization performed better for the dataset with minor batch effects such as for Dataset 1, it was the least effective to remove obvious distribution bias as seen in Dataset 2 and 3. ABnorm, on the other hand, could effectively correct the distribution biases for both datasets and its performance was between QNβ and lumi.

However, when a dataset had more obvious batch effects such as Dataset 2 and 3, lumi normalization became less effective, leaving a larger portion of batch effects intact.

DNA methylation and gene expression data have been processed using the same blood sample, excluding possible batch effects, such as the effect of different time points.

Experiment-wide systematic technical or "batch" effects such as that caused by RNA extraction on different sample batches were removed using Partek Genomics Suite [ 28].

The undesirable variation coming from batch effects, such as sampling time, different technology, can be adjusted with the help of methods implemented in sva package [ 9].

As with any microarray platform that measures quantitative traits, batch effects, such as those associated with chips, plates, runs, time and other experimental and biological conditions, are expected to cause a large variation in parameter measurement.

Re-analysis of our MCF7 and MCF10A Affymetrix datasets demonstrated that not compensating for one batch effect, such as the use of a different scanner (Eg. if the information was not available) would have a much smaller effect on the numbers of genes identified as commonly differentially expressed, than another batch effect (such as the labelling method or if RNA was amplified).

Source of variation was analyzed; non-relevant batches effects such as array type, working batch, patient age and gender were eliminated.

Some of these are due to known technical or biological effects such as batch effects and cell growth stage, which, when not the focus of the analysis, can be removed by fitting them as covariates.

In the presence of technical confounding effects, such as batch effects, the columns will share characteristics that will cause the overall patterns of expression to be similar and thus the arrays will be statistically correlated.

Technical confounding effects, such as a batch effect, typically have a global effect on the data.
