[Pw_forum] not enough bands

[Yonas Abraham]

Hi,

I am trying to generate stm image using pwscf and I am
getting this " not enough bands" error.

I run scf and nscf calculations with out any problem. 
here is some of the information the pp code spites out
just before it died.

is this mean that I have to have some more empty
bands?
