[Wien] [SPAM?] Re: k point parallel calculations

[Laurence Marks]

I am not certain, but it looks like the mixer error for 12/13 is due to a
format error in your case.in0. This may be incorrect, please look at what
is at line 168 of your mixer.F.

In most cases where I have seen errors such as this it is because something
has gone wrong earlier. Check with "cat *.error" as all theses files should
be empty. Check that your case.clmval and case.clmcor are not empty and do
not contain NAN. Look at the end of the case.output* files to check that
the programs really worked.
