[CP2K-user] [CP2K:15518] Data-type problem of wavefunction in gaussian cube files

[jade panda]

Dear Juerg,

Thanks for your suggestion. It helps me a lot. By the way, I have a new 
question: for other k-point than gamma point, the primitive function is 
still real number, but the MO coefficients will be complex number. Is it 
right? Thanks.

Regards,
Jade
