Hi,

I am having trouble processing an image through the Unsupervised KMeans 
image classification in the OTB Toolbox of QGIS 2.4. I have a .tif image in 
the *Input Image *box and keep all the defaults (*shown below) *. 

<https://lh3.googleusercontent.com/-CLNjlxts-E8/VFzhBwR3UgI/AAAAAAAAAFA/frNnND6AQyE/s1600/kmeans.JPG>



Once I select *Run *this error immediately shows up: 

Algorithm Unsupervised KMeans image classification starting... 

unsupported operand type(s) for +: 'NoneType' and 'str' See log for more 
details



I have tried increasing the available RAM (Mb) option as well as saving the 
*Output 
Image *in a file rather than a temp. Nothing has worked. Can anyone shed 
light on this problem for me? Thank you for your help!


Best Regards,


Jason
