Oops, my mistake. I have ##lrm=output raster in the header, but lpf = ...
Is the only line in my code.

I don't get the error message after changing lrm to lpf in the header. I do
get another error message, but I think I broke my processing by trying to
force an update. I'll test it tomorrow. Sorry about the confusion!
