[Pw_forum] TDDFT with turbo_lanczos.x

[henry odhiambo]

Hello users,
 
I am calculating the absorption spetrum. If I run the code turbo_lanczos.x after performing the ground state scf, the calculation stops and I get the error message bellow:
 
*********************************************************************************
from orthogonalize:     error  #   1
degauss with gamma point algorithm
*********************************************************************************
 
Could any one help. 
 
Thank you.
