Abstract
The application of established microarray data quality measures to time course experiments potentially
gives misleading results. In particular, genuine biological variation my be mistaken for technical
artifacts. We suggest tailoring standard methods to time course data by restricting the assessment
to subsets of genes selected on the basis of the experiment. The method is tested on two different
kinds of experimental data sets, one from a developmental process and one from a circadian process.
With these modifications, quality assessment for microarray data can be tuned to appropriately address
the special situation of time course experiments.
