Line 4: \|type=[[ERROR]] \|message_desc=The input grid cell width (dx) is not the same as the cell height (dy) which means that the raster input is using rectangular cells rather than square cells. \|suggestions= \|suggestions=Check the process on how the grid was generated. If exported from another program, check if there is an option to set the output resolution and re-export. If it isn't possible to change the export options (e.g. the raster is downloaded from a government webpage and there aren't any export options) then the raster will need to be converted into square cells using a program like QGIS, ArcGIS, or GDAL. In QGIS, the option to change the raster resolution is available in the dialog after right clicking they layer and selecting "Export >> Save As". If using GDAL (gdal_translate.exe), the target resolution can be set using <tt>"-tr <xres> <yres>"</tt>. * Check the process on how the grid was generated.
