[Pw_forum] how to set nr1b, nr2b, nr3b for cp.x when using ultrasoft pseudopotential

[vega lew]

Dear all,

Sorry for last arbitrary question. I found there was a code called cppp.x.

But now I encounter another serious problem with the information from pp.x
of "ortho went bananas", when I try to add nose thermostat to the system at
150th step.

the process as follows,
First, I get the optimized geometry from the pw.x. Then I use that geometry
as the initial input to pp.x.
During the first 19 of cp calculation, I did a few electronic steps with
ions fixed and dt=1
