subset in out
Takes a rectangular subset of a data set. The given data set and the resulting subset may have up to seven axes. Axes that become degenerate by sub-setting - i.e. along which only one pixel is chosen - are deleted from the subset. Thus the subset may have smaller dimensionality than the original.
subset in(1.5:2.5,10:12) out This takes the data from IN and writes the subset to OUT. The subset is specified as having 1st axis coordinates between 1.5 and 2.5 and 2nd axis pixel numbers between 10 and 12.
