[Wien] DOS vs. k-point

[Chiung-Yuan Lin]

Dear all,
 I plan to plot DOS for a large-unit-cell case.
Normally one k-point is used for a large unit cell to perform SCF.
I just read the discussion in the mailing list by Thomas on May 30, 2005.
It sounds like tetra needs more than one k-point to calculate DOS.
Is this true? If anyone knows a way to calculate DOS with a single
k-point, please let know. Or, someone can confirm to me that this
is not possible.
 Thank you,
Chiung-Yuan
