the v.in.region and g.region vect= steps are redundant, but make sure when
you zoom you update the computational region, not just the display one in

Hamish,
Good to know. Thanks.
I'm a CLI person so I use

I while ago I asked how to cut a small map from a larger one using the

I tried this again:
Approach 1: r.mapcalc
Approach 2: r.re

Did you do:
g.copy rast=boundary_raster,MASK
or alternatively:
r.mask input=boundary_raster -o
(-o for overwrite)
?
