[Pw_forum] using wf_collect only for a few bands

[J. D. Burton]

Dear All,

 

Is there a way to use the 'wf_collect' to save wavefunctions ONLY for a few
bands at each k-point, say +/- 1eV around the Fermi energy? I am trying to
plot k-resolved LDOS on a fine k-grid to image the Fermi surface of a 2-D
heterostructure, but saving ALL the wavefunctions takes way too much disk
space and my cluster administrator starts barking at me.

 

I've looked in the code and I might be able to figure out how to do it in a
very ad hoc way, but I'm wondering if anyone has a quicker solution.

 

Cheers,

J. D.
