MetaImageIO reports all multi-component images as images of vector pixel type. RGBPixels are not vector pixel types. So this warning is saying you are streaming RGBPixels to a Vector image, which doesn't match. If you changed the output image to a image of vector is should go away. </div><div><br></div><div>I think this is reasonable behavior and a reasonable warning for this situation. What do you think?</div><div><br></div><div>BTW: I am curious of you are communicating between each node after each iteration, or are just having a large overlapping region?</div><div><br></div><div>Brad</div><div><br><div><div>On Dec 6, 2010, at 2:16 PM, Kevin H.
