a.
Here I wonder if I can use the phonon eigenvectors directly calculated from
'matdyn.x' as my polarization vector 'e^{\alpha}_{q,\eta}'.
Or do I have to re-normalize the eigenvectors by multiplying masses somehow?
Thank you.

ver=.true.'.
(Of course I could restart from the 'reduce_io=.false.'.)
Could anyone share your experience how to reduce the I/O ?
I'm trying to run 4 group of q-points using 240 cores for each.
So I'm trying to run using total 960 cores which generates and writes total
5*
tr2_ph' and 'conv_thr' when doing
ph.x)
I'm not sure if the negative frequency indicates the 'real'
instability or not..
But as far as I understand from literatures this geometry is supposed
to be stable..
Also, I'm not sure if the 'vc-relax&
ldn't be a problem having considered that the 10~15A of
vacuum region usually is accepted. (Please correct me if I'm wrong.)
Could I ask what you mean by 'it is far from the Si-H system' ?
Thank you very much.

I guess it should not be matter but I just want to be sure ..
Thank you.
