Hi @11niazikhan -

It looks like you are using an Excel spreadsheet (.xlsx) for the biophysical table, but the model requires a CSV (comma-separated value) table. Try saving your biophysical table to CSV and try again. Note that the User Guide has a Data Needs section that details the requirements of each input, such as table format.

Also, you are running a somewhat old version of the model, so I would recommend using the latest (version 3.7.0), which has many bug fixes and we are actively supporting.

Thank you so much i try as per instruction.

Brother, i’ve change Biophysical table format xlsx to csv but also error occur . can you further guide me.Regards

Hi @11niazikhan -

I suspect that there is something about the format of the .csv that is causing the problem. Assuming that you do actually have the required “usle_c” field in the table, look at the table in a text editor (not Excel) and make sure that it is being saved with the values separated by commas (not semicolons or any other character.) Also make sure that there is not a blank line at the bottom of the file, sometimes that causes problems (but maybe this has been fixed in the latest version?)

It is helpful if you post the whole log file (.txt) that the model produces, it gives us extra information that often helps us understand what’s happening. Thanks!

~ Stacie

Thanks, @swolny I try again as your instruction.

Hi @swolny after changing the values in usle_c then this error has occurred, kindly, gave me a solution how I can manage this.Regards

Hi @11niazikhan -

It would be really helpful if you’d post the whole log file - in this case there might be more useful information earlier in the text.

The error “The rasters’ and vectors’ intersection is empty” often means that your input layers don’t all have exactly the same projected coordinate system, so they’re not lining up correctly. That’s the first thing to check, and reproject any that aren’t exactly the same. Also look for watershed polygons that are outside the boundary of the other (raster) input layers, and remove them if they exist, or extend the rasters to cover them.
