Hi

I want to produce the basis sets(TZVP + TZV2P) for copper as what you 
summarized in your slides. Firstly, i followed the example as you printed 
in your slides, but i  can't obtain the result as you got and printed in 
the next slide.Below are my some problems that confused me a lot:
1.I have no idea how to set the PP_BASIS section paramenters(S_EXPONENTS 
and P_EXPONENTS).
2.I got 40 exponents for every momentum in my result, and the maximum 
number of the exponent is 292075412.34116322. it is much higher than i have 
never seen before.Is the error that cause the unreasonable result.
3. And according to your computation result, I can't get the Na CBS as you 
printed the next slide.Is that the format problem?
