Less than two valid focal nodes found. Please check focal node location file.

[schwayne]

In my use of the Circuitscape toolbox, I first converted the point file to a raster using the "Convert features to raster for Circuitscape". I tried this also using the 10m buffers created to represent the polygons of core areas. I then put these rasters into the Circuitscape toolbox and every time I get the error "Less than two valid focal nodes found. Please check focal node location file." I see that it creates a scratch folder and makes copies of the resistance and points as .asc files but it does not seem to go past this step when the error appears. I have also tried taking these .asc files and using the Circuitscape 4.0 but it also gives the same error. This is my first time using the program so I am not sure what I am doing wrong, and would appreciate any help you could give me. Thank you!
