Since you don't specify full path, I suppose that you started fityk in
a different directory than cfityk.
If you want to open file from the same directory as script, there is a
special trick for this, use as path:
_EXECUTED_SCRIPT_DIR_/dataset.txt
> "Fityk can save its state to a script (info state > file.fit)."
> http://fityk.nieto.pl/ref.html

> But it seems outdated, as there's no "info state" command at all.
This command is present in the latest version, and it's not new. Which
version do you use?
