Time series experiments

In this example we take a look at the annotation of a time course. Let’s imagine a study in which our plant of interest (plant1), Arabidopsis thaliana (Characteristic [Organism]), was exposed to salt stress (Component [Ingredient]). To investigate the cellular response, you harvested samples at various time points after exposure to the stressor: S1 is harvested right away, S2 after 10 minutes, and so on.

By using a Factor building block you can annotate the time after exposure and thereby the sampling point in the annotation table. This time period will ultimately result in the given output, when all remaining parameters for treatment and analysis were identical.
