HRU challenge

[MOKUA RETANG (Dr Reti)]

Hi SWAT users

Can anyone assist with the following error when trying to create HRUs.I am not familiar with coding, so I don't know how to interpret and fix this python error

2026-02-27T15:53:42     WARNING    Traceback (most recent call last):
              File "C:\Users/RetangM/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\QSWATPlus\QSWATPlus\hrus.py", line 5569, in readFiles
              OK = self.CreateHRUs.generateBasins(self._dlg.progressBar, root)
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
              File "C:\Users/RetangM/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\QSWATPlus\QSWATPlus\hrus.py", line 918, in generateBasins
              crop = self._db.translateLanduse(int(crop))
              ^^^^^^^^^
             ValueError: cannot convert float NaN to integer

I will appreciate your assistance

Regards

Retang

It looks like your landuse raster is returning a NaN when being read,
which is very strange. If you cannot find the problem in this file send
me your complete project folder and I will investigate.
