There are 2 parts - tabs in the Navigation Bar:
Single gene look-up
Selecting a gene by symbol or Ensembl ID generates (top) a bar plot of TPMs in control (NBH, normal brain homogenta) 10 weeks timepoint samples, and (bottom) a bar plot of log2 fold enrichment between RML and control, for each cell type, both timepoints. You can toggle between invidual (free) scaling and fixed scaling for y-axis.
Dot plot
The dot plot shows each individual gene as a single point. Data is separated into cell types and timepoints. Points can be selected by clicking or dragging a selection box (move the cursor while holding left mous button). Selected genes are highlighted, labeled, and listed in the table below the plot, which can be printed or exported in multiple formats using the widget above the table. 'Reset' button in the side panel de-selects all highlighted genes. Genes can also be de-selected by clicking and dragging (dragging across a mix of selected and not-selected points will invert the selection). The slider in the side panel restricts the displayed genes based on FDR threshold (BH).
