Thanks, it worked and was indeed a silly question

ripes · Multiwfn and wavefunction analysis

Dear developers,

I'm having a problem opening Orca 6 .gbw files. I get the error:

Running: C:\orca5\orca_2mkl.exe "C:\Users\Rino\Desktop\wat\tda_orca6" -molden > NUL
[file orca_tools/Tool-GTO-Bases/basissets.cpp, line 737]: Wrong number of basis-sets stored!
Error: orca_2mkl conversion failed!

The same exact outputs generated by Orca 5 are properly opened, instead. I am using the latest version (3.8, Jan 2026).

Any help is welcome!

This is the test input file for Orca:

! CAM-B3LYP def2-SVP RIJCOSX TightSCF
%PAL NPROCS 32 END
%TDDFT
NROOTS 4
TDA TRUE
END

# test

*xyz 0 1
O 0. 0. 0.
H 0.758 0. 0.504
H 0.758 0. -0.504

BTW, an option to visualize the electric/magnetic moments as arrows in the GUI would be much appreciated...

Thanks, it was indeed the missing tprint making such a large difference. The calculations were tda, in fact.

Dear Tian, dear all,

I just realized that there is a discrepancy between electric/magnetic moments evaluated via 18/5 option and those found in orca output.
For example, Orca:
-----------------------------------------------------------------------------
ABSORPTION SPECTRUM VIA TRANSITION ELECTRIC DIPOLE MOMENTS
-----------------------------------------------------------------------------
State Energy Wavelength fosc T2 TX TY TZ

2 29419.1 339.9 0.019029106 0.00383 -0.01938 -0.04164 0.04143

Multiwfn:
Transition electric dipole moment between ground state (0) and excited states (a.u.)
i j X Y Z Diff.(eV) Oscil.str
0 1 -0.0542044 0.0178488 -0.0468526 3.35200 0.00045
0 2 0.2953035 -0.0586027 1.1293486 3.64800 0.12209

Same happens with magnetic moments. The first input file was generated from .gbw by orca_2mkl ... -molden, the second was the correpsonding .out. I don't know if this is a bug or I am missing something.

Thanks

And then the .out file.... thank you!

Hi all,

I am running TDA-DFT calculations with ORCA. I wish to calculate NTO thereafter
(option 18 -> 6) but whatever file I load (out, cis, gbw, mkl generated from gbw) I always the the error:

Error: The input file does not contain basis function information!

Any hint?

Thanks

Dear Tian Lu,

thank you for the reply. I undestand that the x,y,z components of TDM are already in the program outputs, still it needs some work to draw them e.g. in GaussView. I think it would be a very useful feature to add in your software.

Best regards

Hi everybody,

I am new to the forum though I have been using this fantastic software for some time now.
I wonder if there is an option, which I couldn't find, to visualize transition dipole moments (electric and magnetic).
I am interested in Gaussian and Orca calcualtions, although I know there are troubles with Orca TD outputs.

Thank you for your aattention
