Error using SOLWEIG

[TigerMINATO]

Hi, I'm a student in Japan. I'm sorry for my bad English.
I got an error when using SOLWEIG, and I don't understand, so I came to ask a question.
Here is the error message. "DEM and DSM were raised unequally (difference>0.5m)"
This error only appears on my desktop computer. I am using the same data on my laptop and it does not have this error and works fine. The data that was distributed in the tutorial works on my desktop computer.
What is the problem?

By the way, the desktop computer is made by NEC. My laptop is made by Dell. I have installed Pandas on both of them.

Do you have the same versions of UMEP on both computers?

You have some negative values in your datasets. remove those (e.g. reclassify to 0) and try again.

OK,I'll try it.

Thank you very much. It was caused by negative values in the data. Thanks to you, SOLWEIG worked fine and I was able to calculate.
But why was the older version able to calculate even if there were negative values?

Looking at the code #230 is the reason why the control of differences in min values was included.

Well, thank you for your help.
