and try to look at the result in the sliceviewer. Additional dimensions sliders do not move like the resulting box have only 2 bins in dimensions 3 and 4. In fact it has 50 and 60 bins correspondingly.

@abuts (2014-08-15T17:11:34):
refs http://trac.mantidproject.org/mantid/ticket/9962 This should resolve MergeMDFiles side of the problem

as MergeMDFiles was not calculating average signal/error for boxes.
Sliceviewer still have problem with the slider location

Apparently there has been a shift away from the SliceViewer to MSlice. Therefore this issue can be closed
