Hello, I have run the sample file downloaded from the official website, but the output is an empty TIF file (black picture without any content), is this a normal situation? The Invest version I downloaded is 3.9.2.

Hi @cxuan , could you describe how you’re viewing the model’s outputs?

When I use a typical image viewer (Preview on Mac, whatever the default is on Windows), the outputs will almost always look like there’s nothing there. A GIS application like QGIS can allow you to stylize your outputs so that they make sense. In case you’re unfamiliar with GIS, here’s a tutorial video for how to [stylize outputs in QGIS](https://www.youtube.com/watch?v=sy9vLYz1Qeg&list=PLSFk2iLV3UfNjTf_dBk8bW-7xdx6z5P7J&index=3) and a [similar one for ArcGIS](https://www.youtube.com/watch?v=4a2bwDLb6xs&list=PLSFk2iLV3UfNjTf_dBk8bW-7xdx6z5P7J&index=2).

Let us know how this goes!
