convert chk to fchk file

Diae · 2021-07-03 13:53:56

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.

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.

Dear Tian Lu:
I obtained chk file from cluster system (linux version of g-16), I tried to convert the chk into fchk using windows version of g-16 but the utility says something like below:
****
Bad file opened by FileIO: Unit=1 I= 2 FPrev=***** FCur= 0.
FileIO: IOper= 9 IFilNo(1)= 1 Len= 0 IPos= 0 Q= 10167860
Bad file opened by FileIO: Unit=1 I= 2 FPrev=***** FCur= 0.
FileIO: IOper= 9 IFilNo(1)= 1 Len= 0 IPos= 0 Q= 10167860
Error termination in NtrErr:
NtrErr Called from FileIO.
****

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.
