Hi,

Actually I found my problem: I had NaN pixels in my image. After I replaced 
them with no data values (using the ManageNoData application) the KMeans 
classification worked fine.

Is it still relevant to file a bug report?

Hello Lucas,

I'm having the same problem on a Landsat 8 image.
Did you find a solution?

Hi,

I'm currently trying to process an unsupervised classification on ASTER,

commandline (I get the same from the GUI version).

Error when loading model

It seems that this .txt is the problem but I don't understand why. The classif 
works on non-stripped landsat images that receive exactly the same processing 
chain that the ASTER, S2A and stripped Landsat.

Do you know how I can make it work ?

I attached the files for which the classif is not working.

Thanks in advance,

Lucas.

Well maybe. The application should handle NaN as no data properly.
