This problem is about "LAPW2: semicore band-ranges too large" not for band
gap too large it was by mistake.

  I went through the FAQ [
http://susi.theochem.tuwien.ac.at/reg_user/faq/qtlb.html] and mailing list
and followed all possible ways (PRATT, -in1new, MSR1a, reduced mixing,
removed LOs for heavier atom, reduced rmt, set scf for loose convergence
parameters and all that I came to know from the mailing list and UG)  but I
could not solve the issue.  Could someone test this structure and tell me
what causes the semi-core band-ranges too large [QTL-B] error?
