[QE-users] regarding pw.x not working

[Gaurav Chauhan Ph.D. Student]

respected sir,
                    i am the new user just installed linux and then quantum
espresso 6.5 in it, with parallel version.
i just try to give input file i got error from pw.x that not able to run.
know when i go to run example i got an error:
gaurav at gaurav-HP-ProBook-4330s-A5V96AV:~/quantam_espresso/q-e-qe-6.5/PW/examples/example01$
./run_example

/home/gaurav/quantam_espresso/q-e-qe-6.5/PW/examples/example01 : starting

This example shows how to use pw.x to calculate the total energy and
the band structure of four simple systems: Si, Al, Cu, Ni.

  executables directory: /home/gaurav/quantam_espresso/q-e-qe-6.5/bin
  pseudo directory:      /home/gaurav/quantam_espresso/q-e-qe-6.5/pseudo
  temporary directory:   /home/gaurav/quantam_espresso/q-e-qe-6.5/tempdir
  checking that needed directories and files exist...
ERROR: /home/gaurav/quantam_espresso/q-e-qe-6.5/bin/pw.x not existent or
not executable
Aborting.


i checked the files in BIN folder, they are not executable files, when i
click on them they give a message no software for this file. files have a
arrow mark on upside, that are unusal type.

sir kindly request you to please suggest the solution.
