Error in EnMAP 3.9 - Regression-based unmixing

[Dimitris Poursanidis]

While running the tutorial (https://enmap-box.readthedocs.io/en/latest/usr_section/application_tutorials/urban_unmixing/tutorial.html) using the sample data, apart from the approach that has been introduced in comparison to the 3.7 version, i receive constantly errors, different each time. See the printscreen on the error type. I use QGIS 3.20.3. Any advice? Should i go to 3.22?

Hi Dimitris,
I guess you made an error when you created the Endmember Dataset.

The message indicated, that you used a raster with only one band:

This would be a valid dataset:
