Problem with Global Feature Extractor using Histogram and Global Features

Hello ,
I tried several times to use the "Global Feature Extractor using Histogram & global features" operator as a subprocess of a MCIO (Multiple Color Image Opener) operator but I had every time an error (java.lang.ArrayIndexOutOfBoundsException).
Is it someone would already have used this operator and/or would have an example ?
Thanks,
Chris

I think the "Global Feature Extractor using Histogram & global features" operator is not intended to be used inside "Multiple Color Image Opener" operator. You can just use "Global Feature Extractor using Histogram & global features" operator. Select folder and add name to each class and that's it. Or you can use "Multiple Color Image Opener" operator with Global Feature Extractor from single image. Here is example process: Best,

Thank you for your reply.
Actually I would like to combine local & global features extraction inside MCIO Operator for a purpose of automatic image classification.
I already tried to use one of your former process examples which you had given in the following thread:
http://rapid-i.com/rapidforum/index.php/topic,6105.msg21457.html#msg21457
But it didn't work, the process started to extract features and then failed and I have had the following error message for the "transpose" operator: "No data was delivered at port Transpose.example set input".
Any ideas ?
I would have a second question for you. I noted MCIO & MIO didn't load/open all images which are in the given folders. The format of my images are the same (.png) but their sizes are different (some pictures are very small with dimensions: 16x16). Do you believe that it would be a problem ?
Thanks

I send you PM, if you can send me some examples of your pictures and I will try it. Without the pictures it is hard to say where the problem is.
Best,
