Our study was mainly based on annotated genes. We identified the most significant DEGs by sorting by log2FC value. We selected the top 50 up-regulated and down-regulated genes to draw the gene expression heatmap (Fig. 2). In the top 10 up-regulated DEGs, SHISA7 (shisa family ...
The default view: Nothing fancy, just scrolling and sorting. The value of cell can be copied to clipboard by right clicking on a cell. The column selection view: Left clicking enables or disables a column in the data frame view. Columns can be dragged with a right click to rearrange them...
