GDR has the Tripal Analysis Expression module to view differential expression values from RNA-seq experiments. Information about the different expression datasets on GDR is displayed in Expression Heatmap page. Expression data for the genome associated mRNAs or assembled transcriptome contigs is visualized either on the associated gene or mRNA page, or by creating a heatmap.
To view if your gene or mRNA of interest have associated expression data, search and find them in "Search Gene and Transcripts". Genes of mRNAs that have expression data will have an "Expression" category on the left hand menu of the feature page.

When "Expression" is clicked, the center pane will change to display the available expression data. Hovering over the bars on the chart displays the expression value and more infomation about the sample. Clicking on the bars will open the information page for the biomaterial, which has links to the analysis details page. There are also options to sort or edit the display of the expression data. When the gene/mRNA is associated with more than one analysis page, a dropdown will show up so that users can change the analysis.
