Hello, when I use plot_lr_path to generate the downstream regulatory network of ligand and receptor pairs, a large number of genes and TFS will be generated. How to screen and visualize the concerned genes or TFs in the plot_lr_path regulatory network? I have tried to modify the code of the plot_lr_path function to only retain the genes of interest and generate the x and y axis coordinates of the points and lines, but they cannot be accurately plotted. Can you provide help to complete this task?
