The meta-functionals are not working properly with the GAPW
method (see many discussions in this mailing list).
There is currently no fix available for this.

Dear ALL 
I have test the CP2K.4.1 and G03 at PBE, PBE0 AND TPSS level, the test result is followed:


we can see the different in TPSS is very large, I hope the CP2K expert can explain it. Thanks
test system: H2O basis set :6-31g**the input file is listed here:
