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

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?

Did you find a solution? Thanks Thibaut On Monday, February 12, 2018 at 1:58:46 PM UTC+1, DAVAZE Lucas wrote: Hi, I'm currently trying to process an unsupervised classification on ASTER, Sentinel2 and Stripped Landsat images that receive preliminary corrections (cloud filtering, topographic correction, band ratio etc...). However, the classification fails and I get the following message when using OTB from the commandline (I get the same from the GUI version). Error when loading model S2A_OPER_MSI_L1C_TL_SGS__20160823T173537_A006111_T31TGL_RATIO2_TopCor_Res_30_clip_clean_KMEAN.tif_model.txt 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.
