Exception in Tkinter callback

Sparky is using Python os.fork() to run a stand-alone program peaks2ucsf
that comes with Sparky in order to generate the CORMA spectrum. The
fork routine is not available on Windows, so the CORMA spectrum
capability cannot be used on Windows. This needs to be documented in
the Sparky manual. It should work on Linux and Mac.

Thanks for the help, with the new version, the extension problem has
been fixed, but cormaspectrum still can not running well.

it is stopped like below

Current Sparky versions (3.114 and 3.115) use Python 2.5 which is
included with Sparky. Get the current version of Sparky and your
problem will be solved. You will not need to edit any files.

The problem is I can not load Python extensions directly.

My system is windows2008 server, and with sparky copied in the folder
C:Program Filessciencesparky. And I have python27 in my c drive
instead of python21. I modified the sparky.bat

set SPARKY_INSTALL=c:Progra~1sciencesparky
set PYTHON=c:Python27python.exe

the changing of the spark_install line make the sparky running,
but if I change the PYTHON line, sparky automatically crashed.
DO I need to install python21?

The cormaspectrum.py file is not a command-line program. It is
part of
Sparky code that implements the menu entry Extensions / Spectrum
/CORMA
spectrum described in the manual



http://www.cgl.ucsf.edu/home/sparky/manual/extensions.html#CormaSpectrum

It reads the output file produced by CORMA, so you will have to
install
and run that program to use it. (If you want to know, the import
sparky line will import file sparky/python/sparky/__init__.py__
when it
is run using the Sparky menu entry.)

Dear all,

This is the first time I use this command, but I faced some
problem.

After I press enter with the command line I got information
like below.

C:Program Filessciencesparkypythonsparkycormaspectrum.py
rx_d300_20C.int.1

Traceback (most recent call last):
File C:Program
Filessciencesparkypythonsparkycormaspectrum.py,
line 7,
in module
import corma
File C:Program Filessciencesparkypythonsparkycorma.py,
line 7,
in module
import atoms
File C:Program Filessciencesparkypythonsparkyatoms.py, line
23, in module
import sputil
File C:Program Filessciencesparkypythonsparkysputil.py,
line
13, in module
import sparky
ImportError: No module named sparky

Looks like the problem is from the file sputil.py, which want
import
sparky on its 13rd line. But I did not see sparky.py in this
pythonsparky folder.

Could anybody tell me where I should point this file to. It is the
sparky.bat in the bin folder?

Thanks a lot.
