Can you help me to solve the problem.

You need to use the formchk in G16 Linux version to convert. Notice that chk file is not cross-platform.

You can use formchk utility in Gaussian package to convert chk to fch/fchk. See beginning of chapter 4 of Multiwfn manual for detail.

In the examples in Multiwfn manual, when .out is used as input file, you can also use .log or .LOG.

Hello every one.
I need to convert chk to fchk file for plotting TDM card
I want also to know if multiwfn accepts the .LOG file or just .log and .out as input files.
King regards.
