hi. 
well i'm not sure if I understood your problem but hereby there is a
solution

you just have to edit a polygon map, with the subsection you want, on top of
your raster map ( something like a mask). afterwards you rasterize that
polygon map and using mapcalc operation you can get your subsection.
i hope it helps you
