[pymvpa] Question about the searchlight example

[Valentin Haenel]

Hi,

there is a line in the searchlioght example that i don't understand:

this line is fine, it will convert the one dimensional sl_map back into a 3
dimensional volume.
>     # map sensitivity map into original dataspace
>     orig_sl_map = dataset.mapReverse(N.array(sl_map))

But what does this one do:?
>     masked_orig_sl_map = N.ma.masked_array(orig_sl_map,
>                                            mask=orig_sl_map == 0)

(Although maybe you just ought to point me in the direction of the masked array
utils in numpy:)
