I have just started on Grass last week and am using ver 5.0beta11 on
r.mapcalc does not work for me so that any expression such as
test3 = test2 - test1 (with test2 set as MASK)
test3 = if(test2 != test1, 1, 0)
returns just the intersection of test2 and test1,
and not what I want - which is that part of test2 that does not include
test1 (i.e. test2 minus the intersection).
If anyone has any ideas before I reinstall GRASS please forward them.
