What basis set for GAPW calculations?

[Matt W]

Hi Dawid,

neither is 'more suitable', they are just different 'model chemistries' in 
the Gaussian terminology. 

If you use GAPW/6-31G*/ALL the results should be essentially those you 
would get from a standard QC package - thousands of references on the the 
accuracy of the method.

If you use GAPW/DZVP/GTH then you should get the same results as using the 
GPW method, but some terms are calculated differently. You can use a lower 
cutoff, but there may be an overhead from the atom centred calculations...
