[Pw_forum] Using molecularpdos.x for adsorption on metal-doped graphene

Dear Guido,

I think I found out some issues with molecularpdos.x.

I recompile molecularpdos.x for both v5.3.0 and v5.4.0 in a serial 
configuration.

v5.3.0 input:

rolly at rolly-MacBook:~/QE-530/espresso-5.3.0/bin$ ./molecularpdos.x 
<~/QE_data/MolPDOS/chainH2_onto_H2.in> 
~/QE_data/MolPDOS/chainH2_onto_H2.out2
STOP 1

v5.3.0 output:

      Program MOLECULARPDOS v.5.3.0 (svn rev. 11974) starts on 13Aug2016 
at 12: 1:44

      This program is part of the open-source Quantum ESPRESSO suite
      for quantum simulation of materials; please cite

      Serial version

      Error in routine molecularpdos (5010):

      stopping ...

So, v5.3.0 has a bug :)

Then I repeat the same input for v5.4.0, it works!


      Program MOLECULARPDOS v.5.4.0 starts on 13Aug2016 at 12:10:58

      Serial version

      Molecular orbitals used for projection
      (data for the full system from file 
/home/rolly/QE_data/MolPDOS/chainH2.atomic_proj.xml)
      Atomic wavefunctions used:    11 -    12

      Projecting onto eigenvectors number:     1 -     2
      (of the subsytem described in file 
/home/rolly/QE_data/MolPDOS/H2.atomic_proj.xml)
      Atomic wavefunctions used:     1 -     2

...

JOB DONE.

One thing I noticed that for molecularpdos.x, the input commend differs 
from pw.x, dos.x and projwfc.x.

It DOES NOT work with: molecularpdos.x -inp file.in |tee file.out,
but it DOES work with: molecularpdos.x <file.in> file.out

What a surprise and I was taken for granted a consistent input commend 
for all QE executables.

Hope it may help someone.

Regards,
Rolly
