[CP2K-user] How to do a correct TDDFPT

Dear cp2k users,

I am intending to do a tddfpt calculation to get the 10 possible first 
excitations for negatively charged-Nitrogen-vacancy center in diamond. The 
system has negative charge and as a result has got triplet excited states 
as well. Really appreciate it if someone could help me to make the input 
file as it should be.  currently I get the error " XC_DERIV method not 
implemented for GPW-LSD!"
