An example of explorative data analysis in dictyExpress. An example of transcriptome exploration steps enabled in dictyExpress. The user starts with a selection of an experiment and a set of genes (A). The user continues by selecting a target gene profile from the dendrogram (the pufA gene) (B). The application automatically highlights the corresponding trajectory in the profile visualization (C). The next step is a request to find and display of list of similarly expressed genes (D). The user can select a subset of the most similar genes, making this list the active set of genes, with a subsequent update of all the dictyExpress components, including the one showing the gene expression profiles (E).
