Dear Shamik,
I wonder if your problem comes not from using wien2k but from using
the batch system when submitting wien2k jobs.
In our supercomputing center, when submitting
a job, the job is appointed its own unique variable SCRATCHDIR.
Further, on our center you have to specify

No,
WIEN2k is still limited to 999 inequivalent atoms.
It is basically a matter compatibility. Currect struct files have lines:

atoms
and not 1128. If I erase one space in the case.struct file
x sgroup thinks I have 128 atoms.
Thank you very much

five or ten times more calculated points would be OK.

There is an alternative way. You may use the
