You're probably not running the script from where the .py is, but from where GRC started. Relative paths are relative to that folder.
That means that if you run gnuradio-companion from your home directory (which is probably the default when you just open it from some menu), then paths are relative to /home/user1.

Easy question here. I'm trying to use a relative path with file sink/source. It errors out with "can't open file".

I'm assuming the path is relative to the location of the .grc file location.

If the location of the .grc file was: /home/user1/proj1/devel/myfile.grc
And a data file was here: /home/user1/proj1/dat/datafile.dat
Then the path I use in file source is: ../dat/datafile.dat

What do I need to change to make this work?
