[Pw_forum] Error in TDFPT calculations

[meysam pazoki]

Dear PWSCF users,

I have encountered the following error in my time dependent density
functional perturbation theory calculations , i am using the turbo_lanczos
program from TDDFPT package for a perovskite material.
At first i have the scf calculations from pw.x at gamma point and then
turbo lanczos program. But i have this error >

 Error in routine lr_readin (1):
     turboTDDFT is not exteneted to metals

I appreciate if somebody can help me to solve the problem. I should say
that the material is semiconductor (from calculated DOS ) but in the scf
output file i have one FErmi level reported in the material band gap !
instead of having highest&lowest occupied(onoccupied) energy levels!

Here are the input parameters for turbo_lanczos.x

Thanks in advance
Meysam
