Thanks, Tian.  The column labels scroll on so fast I missed them above the new set of options.  The graph that I get plotted goes 0 to 14.81 Bohr on the x-axis, and 16.76 on the y-axis.  In the text file, the 4th column (x) goes from 0 to 7.83896 and the 5th column goes from 0 to 8.86786 in the sets of 200 for the grid points. 

I don't understand why the graph axis values and text file axis values are so different.  Can you clarify why the difference between the plot and the saved file?  Thank you.

Thank you very much, Tian!  I was focused on section 4.4, not 4.5.  I was able to follow the example provided in the manual very easily with my files which shows how well the manual is written.  I used Option -6 to export the calculated plane to a text file which is also a very nice feature to have:

15.42593   8.11226  -0.17794   0.00000   0.00000  2.4373344965E-03
15.38293   8.10101  -0.17471   0.00000   0.04456  2.6856696917E-03
15.33993   8.08977  -0.17148   0.00000   0.08912  2.9467572067E-03
.

.

I have a 200 X 200 grid so the rows cycles in 200 units.  I think the 1st column is the x-axis value, 2nd column is the y-axis value, 3rd column is the z-axis value for the electron density redistribution.  I can't quite figure out what the 4th, 5th, and 6th columns are.  Can you help me out here.

Again, thanks for making this electronic structure analyzer available to the public.  It is most appreciated.

I study the adsorption of organic acids on FeOOH mineral surfaces. Using Gaussian16, I run where the molecule is adsorbed on the FeOOH, the molecule alone, and the FeOOH alone. Using cubegen and GaussView6, I can can get the the *.cub file that represents the electron density redistribution when the molecule is adsorbed to the mineral by adsorbed - molecule alone - FeOOH alone.

Can multiwfn read the *.cub file for electron redistribution and produce a contour plot showing where the regions of of density gain and loss?  Thank you.
