    text
    copied!<p>I'm trying to call current PyMOL session from python script (wxpython GUI), and then load some data from PyMOL and send few commands to PyMOL. At the moment I can open a new PyMOL session in python script:</p> <pre><code>import sys, os from wx import * app = wx.App() dialog = wx.FileDialog ( None, message = 'Set PyMOL directiry', style = wx.OPEN) if dialog.ShowModal() == wx.ID_OK: # Pymol path moddir = dialog.GetDirectory() sys.path.insert(0, moddir) os.environ['PYMOL_PATH'] = moddir import pymol pymol.finish_launching() else: print 'Nothing was selected.' from pymol import * dialog1 = wx.FileDialog ( None, message = 'Set PDB file', style = wx.OPEN) if dialog1.ShowModal() == wx.ID_OK: pdbfile = dialog1.GetPath() cmd.load(pdbfile) else: print 'Nothing was selected.' dialog.Destroy() app.MainLoop() </code></pre> <p>BUT actually I'd like to check in my python scrip whether any PyMOL session is already opened. I found discussion corresponding to this topic here: <a href="https://stackoverflow.com/questions/11858681/only-call-function-if-pymol-running">Only call function if PyMOL running</a> Following this discussion I tried to call 'print' function in PyMOL:</p> <pre><code>try: from pymol import cmd print 'Connected' except: &lt;open new Pymol sesssion&gt; </code></pre> <p>but I do not see any text in PyMOL cmd. I tried to determine PyMOL path before this statement and again I failed. </p> <p>Does anyone know how to call current PyMOL session from python script? </p>
