Shift global data

Hi,

Is there a good way to shift global GFS data so that the raster data
corresponds to a longitudes from [-180,180[ instead [0, 360[?

I'm interested in cut a region over Europe using the following convention:

smallArea = globaArea['lat_0|X1:X2 lon|Y1:Y2']

but since my region crosses the 0 long, I dont know how to use it...

any ideias?

Tks !!
