ORCA provides a convenient way to plot orbitals and densities (alright, not so convenient) in the form of a small binary called orca_plot. This text-based interface (Figure 1) allows you to select what you want to plot, the grid quality and the output for the plot.
As easy as it is to plot one surface this way, it can easily become annoying to do it several times if you need to plot several surfaces. The good news is that you can plot using non-interactive mode too by just piping a series of numbers to the binary. So, instead of typing the options sequentially like this: 1, 1, 3, 0, 4, 120, 5, 7, 2, 54, 10, 11 you can just put the numbers in a text file, line by line:
1 1 3 0 4 120 5 7 2 54 10 11
Save it as a txt file (or whatever, like PLOT.txt) and concatenate it to the orca_plot software:
orca_plot RDB_Se_a.$i.gbw -i < PLOT.txtYou can even repeat the operations for a bunch of GBW files if they are sequentially ordered like this in Figure 2 using a little shell scripting:
for i in {001..040}; do orca_plot RDB_OSSe_NH.$i.gbw -i < PLOT.txt; done
