There should be nothing wrong with the command you posted telling the script to make zoom level 16, and I have verified that the same command works fine for my setup.  The error you are receiving about multiple input files suggests the script believes the second file path you gave it is another raster to tile which it clearly is not.  Try either adding a trailing slash to the path (`C:\\GeoPackage\\Suitability\\Tiles\\`) or alternatively you can tile all over again with the `-z 9-16` flag into a new directory."}}
