DFTB skf files input

[Sushi]

Oi,

in the manual (https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/DFT/QS/DFTB/PARAMETER.html) it is described, how I should provide skf files for DFTB calculation as an input (SKF Keyword followed by 3 words), but I am seriously wondering what three keywords the input is requesting (I could understand 2 (O O for oxygen oxygen for example), but what is the third keyword?)

Moreover I am wondering, whether I can use the files provided by https://www.dftb.org/parameters/download/halorg/halorg-0-1-cc/ without modifications?

Thanks in advance
Cheers
Sushi

Hi

the third keyword is the name of the parameter file

&PARAMETER
SK_FILE C C cc.spl
SK_FILE C O co.spl
SK_FILE O C oc.spl
SK_FILE O O oo.spl
&END PARAMETER

Usually, the files from dftb.org work unmodified. However, you
better test extensively as we never know if we have covered all
possible exceptions of the file format.

regards
