This is a little bit more complicated if the DOS is calculated with a k-mesh that is not the same as the one used during the scf calculation. After completion (and save_lapw) of the scf calculation, you need to follow the steps explained in section "Starting a calculation from another k-mesh" on page 54 of the user's guide (use the option "-i 1"). After that you can execute x lapw2 -hf -qtl -p x tetra -hf etc.
I guess that you changed the k-mesh for the DOS, and the problem of your procedure is that "x hf" was not executed in order to generate case.vectorhf for the new k-mesh. FT On Friday 2018-02-16 14:31, chin Sabsu wrote:

Mailing List for WIEN2k Users <wien@zeus.theochem.tuwien.ac.at> Subject: [Wien] query for -hf with lapw2 for properties Dear Wien2k Tran Sir and others, Do we need to put -hf switch with "x lapw2" when calculating the optical and doss properties from YS-PBE0? Without -hf I got optical and DOSs without any error but when I use -hf with lapw2 I am getting an error: LAPW1 END LAPW1 END LAPW1 END FERMI - Error LEGAL END TETRA LAPW1 END LAPW1 END LAPW1 END FERMI - Error OPTIC END OPTIC END OPTIC END JOINT DOS END However, properties respective files are generated. Also, I used a 2x2x2 mesh (with 4x4x4 mesh one one scf cycle was taking more than 24 hrs and still not finished) for scf it gave me 3 kpoins in ibz and 8 k-points in fbz file. I did not increase the k-mesh for band structure and optical properties as it takes much time (it is reported in the mailing list by someone that their calculations are taking a week to finish). Thanks for any suggestions! regards Chin S.
