[PyMOL] piping pymol from a tcl/tk interface on Windows

[pierre mazet]

Hi all,
I want to send pymol command from a tcl/tk GUI. To begin, I just want to
open pymol and load a pdb file when I click on a button. I'm using pipe.

here is my code:

button .b1 -text "pipe" -command "runPymolAndLoad"

proc runPymolAndLoad {} {

  set fl [open "|pymol -p" w]

  set opt "load structure.pdb"
  puts $fl $opti
  flush $fl
}

This works on Mac ! ...  but not on Windows !!

Do someone know why ?

I've tried : fconfigure $fl -blocking no
but it doesn't work neither...

Thanks in advance for your help

Cheers

pierre.
