[GRASS-user] Interpreting r.watershed accumulation map

[Laurent C.]

Richard,

It seems to be a problem from within the temporal framework. I never
had this specific problem before, but I've run into some other obscure
errors using TGRASS.
Are other temporal commands (t.list, t.create...) working properly?
