Hello Jan,

I also agree to Francis' suggestion. Here are some more details (on
Windows 10). The following lines have to go to an Igor text file (.itx).
Just assume a Python script generated these lines. The file name in this
example is IgorInstructions.itx

IGOR
WAVES /D 'dataset_1'
BEGIN
??? 1
??? 4
??? 9
??? 16
END
X Display 'dataset_1'
X NewPath /O /C SaveDir "C:Users:Admin:Desktop:Test"
X SavePICT/E=-5/B=72 /P=SaveDir /O
X Quit

(Please adapt the path to a suitable location on your hard drive.)
The program executes the following steps:

1. Load the data
2. Make a plot
3. Make a new folder on the hard drive
4. Save the plot there
5. Quit Igor

You can "start" the Igor text files in two ways: either double click it,
or go the command window (DOS prompt), navigate to the folder that
contains "IgorInstructions.itx", and type :????? start Igor.exe
IgorInstructions.itx

I think you can also directly use Python to send the last command (
start Igor.exe ....... etc) to the command line but I have not tried
this myself.

The code above is a simplified version of example 8.13 from "Programming
Igor Pro: A Comprehensive Introduction" (just in case you need more
details).

Best,

MS
