Hello,

thank you Damien and Matthieu.

I had a look at the original papers from Goedecket et al. I am not a specialist of pseudos but it seems that HGH are a generalization of GTH so it should be possible to use GTH instead. I am going to try this.

Thanks again
Pascal

channels. This pseudo is used in particular by the bigDFT people, so
we should hear from them whether it will be easy to generalize. I
don't know gth too well - could you use hgh instead? That one is
certainly general and goes up to f projectors.
    
The HGH pseudo-potentials go up to f projectors. I know that the
question was for GTH and not HGH, so the answer may not be usefull :|

The k coefficients in GTH are used only for spin-orbit coupling, so may
be not in your case, you can let zero for them.

By the way, in BigDFT GTH, we limit also to the s and p channels.

Damien.
