[CP2K-user] [CP2K:14798] How to generate electron density cube file from tdwfn file yielded by TDDFPT?

[hut... at chem.uzh.ch]

Hi

unfortunately, there is no well tested way to do this. In the current
version, if you are using the new TDDFT code

CP2K_INPUT / FORCE_EVAL / PROPERTIES / TDDFPT 

You can find 

CP2K_INPUT / FORCE_EVAL / PROPERTIES / TDDFPT / PRINT / NTO_ANALYSIS
and
CP2K_INPUT / FORCE_EVAL / PROPERTIES / TDDFPT / PRINT / MOS_MOLDEN

This might be what you are looking for. However, this is work in 
progress. Double check for correctness and consistency!

regards

Subject: [CP2K:14798] How to generate electron density cube file from tdwfn file yielded by TDDFPT?

Hello, cp2k users and developers, 

I want to analyze electron population of excited states, however, I failed to find ways to generate cube files of excited states like ground state runs where I just need to activate PRINT subsection in DFT section. 
I have looked up manual and even tried to use tdwfn file as input of WFN_RESTART_FILE_NAME parameter directly but program raised an error. Indeed, the size of tdwfn file seems not contain information in the same format as that of wfn file. 
So how can I obtain e. g. electron density cube file of excited state? 

Any helps will be appreciated.
