[Pw_forum] can't read wavefunction and coords

Gabriele,

I am almost there. I appreciate you helping me
I added coordinates, read nicely. However when calculating DOS in produces empty dos2 and pdos output files with no error and doesn't generate fildos at all. I suspect it has problems reading guess

I am confused as I am following Example 8, thus should be pretty straightforward but it's not.

My latest input is below
