[modeller_usage] How can I get MolPDF of an existed PDB file of an model

[Yun He <>]

When I use automodel class to generate N models, the energy MolPDF of every 
model will be displayed in the log file, e.g.
===========================================
>> Summary of successfully produced models:
Filename                          molpdf
----------------------------------------
T0291.B99990001.pdb           2029.54651
T0291.B99990002.pdb           2719.03467
T0291.B99990003.pdb           2009.53479
T0291.B99990004.pdb           2688.20435
T0291.B99990005.pdb           2311.00342
===========================================
But, sometimes, after the models got be refined by some other means, how can I 
get those changed molpdf by handling the existed PDB files, rather than to 
involve the automodel class again to rebuild such models?

I think "examples/commands/energy.py" in node151.html of the manual may help 
me, but I wonder whether the molpdf got by this method is identical to that 
recorded in log file.
