You can directly copy data from command-line window to a plain text file, please check Section 5.4 of Multiwfn on how to do that.
IBSIW based on IGMH may be better, though I didn't perform a rigorous comparative test.
Hello Multiwfn users
How to print the results of IBSI calculation in a text file ?
who is better for studying weak interactions between tow fragments: IBSIW (IGMH high grid quality) or IBSI (IGM prom; medium grid quality)
Thanks in advance.
