Dear Peter,
          thank you for the help on the f-7/2 projections. I was able to 
get the f-7/2 projection of the DOS to work well for the simple Hf example 
that you suggested.

However, when I attempt to use QTL on my f-system which is Yb based I 
receive strange errors. With QSPLIT=0,-1 I receive: *** glibc detected *** 
malloc(): memory corruption: 0000000000071eb00 *** forrtl: error (76): IOT 
trap signal

and the process hangs in the shell. If I remove the Yb atoms from 
consideration in case.inq the problem disappears. Also, I attempted 
removing some orbitals from case.inq for the Yb atom, but the problem still 
occurs even if I only consider the s(L=0) projection.

With QSPLIT=-2 I receive: forrtl: severe (64): input conversion error, unit

upqtl.error simply reads 'Error in QTL' I looked through the other output 
files and can not find any information about the error.

Thank you for any help,
David.
