Thanks, I am even further in your debt. This indeed does work.

Is there a way to know from the CIF file alone that one has to change natrd to 2? I might have figured this out for spacegroup 227, but if I'm using an arbitrary spacegroup, how do I know? Do I just need to keep a big database of every spacegroup, and the corresponding values? I would like to be able to set this up to use a minimum of user intervention.

I'll spend some time reading through the relevant test files, as you suggested.

Thanks very much for your help with this.

Dear Rick,

There are several errors in the input. I have corrected it, as shown below.
(Other parameters may be tuned... but they are not the problems here.) You
might want to check test cases using "spgroup" "natrd" in ~ABINIT/tests/*.

Good continuation,
Masayoshi
