[Pw_forum] problem with input redirection with plotrho.x

[Glenn Johnson]

I am a newbie to pwscf so have patience.  I just compiled pwscf-1.2
with Linux IFC-7.1, Build 20030307Z.  I downloaded the pseudopotentials
from the pwscf.org Web site for the elements needed for the examples
and then I ran all of the examples.  I did have to change the names
in the run_example scripts to match the names of the downloaded
pseudopotentials.  Everything seems to work fine except for two things:

- In example2, I get a "FORTRAN STOP 1" at the end of the "phonon
  calculation at X for a single mode".  The output seems okay though.

- In example5, I get an error with plotrho.x (see below).  The error
  is due to redirection of the input file to plotrho.x; if I execute
  plotrho.x without input redirection and enter the appropriate values
  when prompted, the program works fine.
 
 running ./run_example:
 This example shows how to use pw.x and pp.x to calculate the
 the scf charge density and plot it in the [110] plane.

Input/Output Error 153: Input file ended

   In Procedure: main program

Here is the output into si.plotrho.out:

   usage: plotrho  [input file] 
 r0   :   0.0000  0.0000  0.0000

 tau2 :   0.0000  0.0000  2.0000
   2 atomic positions read

I looked at the Fortran code in plotrho.f90 but nothing jumped out at me
as being wrong.  Has anyone seen this before?

Thanks.
