Hi,

I need the CI-vectors from a TDDFT calculation. After the TDDFT calculation, a binary file, tddft.civecs_singlet, is generated. Is there any code to extract the CI-vectors from this binary file?

Thanks,
Md. Elious Ali Mondal

Hi Elious,

There is no standalone utility code for this with the NWChem distribution at the moment. But, you can write a simple one based on where the CI vectors are printed out in tddft_analysis.F. This file is also read in the tddft_gradients and dplot modules.

Best,
-Niri
