Words similar to log-ratios
Example sentences for: log-ratios
How can you use “log-ratios” in a sentence? Here are some example sentences to help you improve your vocabulary:
First, a gene was excluded from the analysis if its average mean intensity above background for the least intense signal (Cy3 or Cy5) across all experiments was ≤ 2,000 or its average spot size across all experiments was ≤ 30 pixels; and second, a floor and ceiling of 0.02 and 50, respectively, were applied to the individual intensity log-ratios.
Moving the median or mode of the log-ratios to zero makes the assumption that the majority of genes are not differentially regulated.
The CaCO2 sample was labeled with Cy3 and the PA-1 sample was labeled with Cy5; genes that are expressed in colon at much higher levels will, therefore, have negative log-ratios and ovary genes will have positive log-ratios.
Scaling the individual Cy3 and Cy5 log-signals before qspline normalization is shown to correct for some of this effect, although this method does not directly scale the R / G log-ratios.
For each gene, we fitted a linear regression model of the log-ratios to the time points, where the model included a separate intercept and coefficient term for each of the three drugs:
