How to change settings directory to run gnuplot on linux [solved?]

[MacKris]

Hi, I'm a chemist trying to use the python script GaussSum.py with gnuplot for creating dataplots, and need some help. Whenever I try to produce a plot from the GaussSum GUI I get the error

sh: line 1: /Users/kristine/Desktop/GaussSum-1.0.5/gnuplot400/bin/wgnuplot.exe: No such file or directory

in my terminal. At the moment, I have gnuplot in the path /usr/local/bin instead. So I need to know how to change the settings directory to enable GaussSum to call gnuplot. Can anyone advise me on what or where to edit in the script please? I've pasted a section of the GaussSum.py where I'm guessing should be editted.

Thanks in advance!

I guess sometimes when having problems with Python stuff, so I will guess here. Have you tried to determine your current value of 'sys.path[0]? If it is '/Users/kristine/Desktop/GaussSum-1.0.5', you may try substituting your path here:

 else: # Initialise the settings file (and directory)
                if not os.path.isdir(settingsdir):
                    os.mkdir(settingsdir)
                self.settings={'global settings.filetype':'Gaussian',
                               'global settings.gnuplot':os.path.join('usr', 'local', 'bin'),
                               .......
 

Sometimes I get lucky, but not usually the first time.

Looks like the key is here:

    def readprefs(self):
        # Check for GaussSum.ini in $HOME/GaussSum1.0 (XP)
        # or $HOME/.gausssum1.0 (Linux)
 
        appdata=os.getenv("HOME")
 

My guess is that the since $HOME is /Users/kristine/Desktop/, you need the /GaussSum-1.0.5 directory there with /gnuplot400/bin/wgnuplot.exe in it.
If you don't want the directory there, look in the .gausssum1.0 file and change the path if it's in there.
Good luck,
Barton
