[…] p-values of <0.05 and an absolute fc of >2 were considered to be degs. as shown in fig. 1, blue represents the data prior to correction and the middle line represents the median (fig. 1a). the limma data package was used to correct the original data (fig. 1b). the results showed that 153 genes between the sclc and the normal group (119 upregulated and 34 downregulated genes) differed […]

limma is a tool for reading, pre-processing, manipulate, quality control and analyse microarray data from a variety of different technologies. In my opinion, it could easily be considered the state-of-the-art tool for analysis of these kind of data. Linear modelling extended by limma provides a powerful way to analyse simple or complex experiments, allowing full control over covariates and time-series designs. Also, the team behind the tool made great effort in creating a tool easily accessible to non bio-statisticians, which is a plus in a lot of ways. Besides, I should also point out that limma has the capability to analyse RNA-seq experiments as well. Finally, users should definitely check the comprehensive (and well-written) limma User Guide, a document that will provide all the basics to get things rolling with the package.
