[Qgis-user] Problem with contour algorithm

I did this yesterday and it worked fine for me, but my command has:

  -f "SQLite" /tmp/xxx/OUTPUT.sqlite

Instead of the -f parameter in your screenshots.  I'm not sure how to
change this - can you see any options that let you select this output
format?

I am just wondering whether the two formats you've selected need
additional parameters.  The SQLite format appears not to need anything
else.

Cheers,
Adam.
