Dear all,

I'm trying to use Random Forests for classification, i use otbcli_TrainImagesClassifier with Pleiades images, it works fine with multispectral images but when i tried the same thing with panchromatic images i got this error :

OpenCV Error: One of arguments' values is out of range () in cvGetCols, file /build/buildd/opencv-2.3.1/modules/core/src/array.cpp, line 1357 2014 Mar 17 16:18:45 : Application.logger (FATAL) The following error occurred during application execution : /build/buildd/opencv-2.3.1/modules/core/src/array.cpp:1357: error: (-211) in function cvGetCols

Could someone plz help me to solve this problem?

Thank you,
Walid
