[Pw_forum] Run ni.scf.in Example

[nebiha ben sedrine]

Dear Pwscf users,

I'm just beginning with PWscf, and after all the installation process with libraairies and related softs,
I am tryig to run as example "ni.scf.in". I have copied pw.x into the example directory, but no succes. 

Here you can find the error messages after running in both PWgui (1) and from a command line (2).
1) couldn't execute "pw.x": no such file or directory
couldn't execute "pw.x": no such file or directory
    while executing
"open [concat | $args] r"
    ("exec" arm line 18)
    invoked from within
"switch -exact -- $mode {
    open {
        set count [incr nonblocking(counter)]
        set nonblocking(status,$count) 1
        return $count
    }

    exec {
        ..."
    (procedure "::tclu::nonblocking" line 4)
    invoked from within
"::tclu::nonblocking exec 12 pw.x < /home/tgharbi/espresso-4.0/PWgui-4.0/examples/pw/ni.scf.in 2> /home/tgharbi/espresso-4.0/PWgui-4.0/examples/pw/ni.s..."
    ("eval" body line 1)
    invoked from within
"eval ::tclu::nonblocking exec $execID $runCmd < $run(inpFile,$moduleObj) 2> $run(errFile,$moduleObj)"
    (procedure "::pwscf::run::run" line 89)
    invoked from within
"::pwscf::run::run ::gUI0"
    invoked from within
".gui0.shellchildsite.menubar.menubar.run.menu invoke active"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list $w invoke active]"
    (procedure "tk::MenuInvoke" line 50)
    invoked from within
"tk::MenuInvoke .gui0.shellchildsite.menubar.menubar.run.menu 1"
    (command bound to event)

2) bash: pw.x: command not found

thank you in advance for your reply
Best Regards
