It is best to upload your screenshot. I can hardly understand your situation.

Sir, After doing IRI analysis I obtain output .txt then copying IRIscatter.gnu to Gnuplot. then running gnuplot IRIscatter.gnu in GNUPLOT folder. I found gnuplot iriscatter.gnu
         ^
         invalid command
What to do to view IRIscatter .ps.
Yours sincerely,
Partha

You are right, https://cloudconvert.com/image-converter works well.

Thanks a lot prof. Tian Lu issue resolved. I got .ps file
Here i would like to say after getting .ps file you can convert it from online file converter like .ps to pdf format no need to install irfanview and other stuff.

Please do not install gnuplot on default path (i.e. C:\Program Files\...)

prof. Tian Lu i tried to plot RDG scatter colored plot but not getting .ps file
I followed all steps as shown in your video also i used cmd, here i am attaching error
please help me

Dear Louis-Charl,

Please check Section 4.A.14 of Multiwfn manual, you can use a VMD plotting script named showcub.vmd to easily draw very nice isosurface map based on cube file exported by Multiwfn.

Best regards,

Hi there

What command prompt can I use to generate a high quality image for fukui function or dual descriptor when using VMD?

Thanks in advance

This is content of script file of gnuplot. You should use gnuplot to run it, rather than directly input the path of this script file in cmd window (Windows system opens it using notepad by default). Please carefully check my video tutorial.

set terminal postscript landscape enhanced color 'Helvetica' 20
set encoding iso_8859_1
set output 'RDGscatter.ps'

Above is the information from the notepad file

I can't quite understand your description. It is best to always upload screenshot so that I can clearly understand your current situation.

I managed to enter the cmd environment now and the command prompt seemed to work but it gives me a notepad file. Should I edit it to get the PS format of the 2D RDGscatter?

Thanks in advance

I can't give you specific advice remotely. So, simply use Powershell or enter cmd in tradition way.

I managed to save it as a .reg file now but is unable to find an entry into the cmd environment

I think the problem I'm encountering is to get it into a .reg file
