[Wien] About optic code in WIEN2k_11.1 (Release 5/4/2011)

[Dr. Sharat Chandra]

Hi

I have a report to make about the optic code included in WIEN2k_11.1 
(Release 5/4/2011).

I am using the WIEN2k on a Fedora 12 system with ifort (IFORT) 10.1 
20080602.

I am calculating the optical constants for Si diamond structure crystal. 
(lattice parameter 10.270700 atu, Si at (1/8,1/8,1/8). My Si.inop file is 
given below (just the default file from case.inop, where I have put the 
proper number of bands in line 2 for NBvalMAX):

-----------------------------------------------
99999 1       number of k-points, first k-point
-5.0 3.0 4    Emin, Emax for matrix elements, NBvalMAX
2             number of choices (columns in *outmat):
1             Re xx
3             Re zz
OFF           ON/OFF   writes MME to unit 4

Choices:
1......Re <x><x>
2......Re <y><y>
3......Re <z><z>
4......Re <x><y>
5......Re <x><z>
6......Re <y><z>
7......Im <x><y>
8......Im <x><z>
9......Im <y><z>
-------------------------------------------------

When I run the command: x optic, I get the following error:

  emin,emax,nbvalmax  -5.00000000000000   3.00000000000000         4

--------------------------------------------------------------

This input file runs properly with the optic package included in 
WIEN2k_09.2 (Release 29/9/2009).

I am not able to understand where is the error coming from as the codes 
in both the versions are quite different.
