I have a classification of vegetation communities across a landscape in a .tif format. I wanted to use the GRASS Zero-Crossing Edge Detection tool in QGIS to help define boundaries between my classes-at the moment the edges of each class are rather speckled and I would like a clear defined boundary. However when I run the tool, I get the following message: "The above files could not be opened, which probably indicates that they were not correctly produced by the executed algorithm". It then goes on to say that "GRASS seems to be correctly installed and configured".
I think the problem is possibly with the input file as in the help page it says the type should be "string". However if I convert my file to an .asc the tool will not let me select it as an input.
Has anyone used this tool before? If so, do you have any idea of what the problem is?
