[GRASS-user] trouble with addons - was: dilation & erosion (mathematical morphology)

Thu Feb 5 07:15:02 PST 2015

you should be able to install the addon from within GRASS using g.extension
or via the menu (settings - addon extensions). If you mean with 'standard
user' an user without administrative privileges, then yes, I think you
should be able to install the addons, they are normally installed in a
hidden folder (.grass7) in the home folder.
