[Pw_forum] Example-29, NOTE : eigenvalues are not computed without ortho.

[joaquin peralta]

Dear espresso users,

I'm running some examples of espresso, in order to understand some variables
and settings used principally in MD capabilities. I ran the example-29 in
order to understand more about the ensemble-DFT and the correct way to use
them.

I ran the example, and work fine, however if I augmented the number of steps
and run again (cleaning all previous information) I obtain the message (each
iprint step):

......
Step     9      10     -7.57021     -7.70233     -7.70223     6
NOTE: eigenvalues are not computed without ortho

Step    10      12     -7.57024     -7.70236     -7.70223     6
......

The eigenvalues are not calculated, but why?, it's correct? if the example
use the option :

orthogonalization = 'Gram-Schmidt'

I remove the orthogonalization option in order to see what happen and the
message disappear, however i don't understand because the reference and
README file show that eigenvalues are calculated. Surely I forget something
or have a mistake with input_file, but i don't see that.

Thanks in Advance
