Hi Henrike,
I need to know which files are opened in the EnMAP-Box, when you start RasterMath. Try to break it down to a single raster file, that causes the problem.
Now, I would need that file to reproduce the error.

[Henrike Dierkes]

I tried it with different files, the example data and my own files.

But I checked it again. Now it works. I couldn’t figure out, what could have caused the error. Will check it again

Seams to be a non-issue, re-open otherwise.
