Use GEO2R to compare two or more groups of Samples in order to identify genes that are differentially expressed across experimental conditions. Results are presented as a table of genes ordered by significance. Full instructions
How to use
Log-transformation has been applied to the data. You can change this in the Options tab.
Calculate the distribution of value data for the Samples you have selected. Distributions may be viewed graphically as a box plot or exported as a number summary table. The plot is useful for determining if value data are median-centered across Samples, and thus suitable for cross-comparison. More...

Category of Platform annotation to display on results.
If you edit Options after performing an analysis, you must click Recalculate on the GEO2R tab to apply the edits.
This tab allows you to view a specific gene expression profile graph by entering the corresponding identifier from the ID column of the Platform record. This feature does not perform any calculations; it merely displays the expression values of the gene across Samples. Sample groups may or may not be defined for this feature to work.
