*Hi all,I'm trying to launch a SVM classification on a raster with 34 bands
like this :*
------------------------------------------ COMMAND
---------------------------------------------------
/usr/local/bin/otbcli_TrainImagesClassifier -io.il Raster_34bands.tif
-io.vd Shp_Apprentissage.shp -io.imstat XML_Raster_34bands.xml -sample.mt
1000 -sample.mv 1000 -sample.edg false -sample.vtr 0.5 -sample.vfn Class
-classifier libsvm -classifier.libsvm.k linear -classifier.libsvm.c 1
-classifier.libsvm.opt true -io.out SVMModel_Raster_34bands.model
----------------------------------------------------------------------------------------------------------------
*On my computer, I get this error :*
------------------------------------------ ERROR

*I think there is not enough memory on my computer, **so I launched the
same command on *
*a server with a larger memory.I get a another error :*

*I don't understand why !!! I checked paths of the files and they are
correct.I launched this command on a raster with a band and it works.The
server responsable gave me the out GDB :*
