[GRASS-user] i.pr: screen does not show map

[Daniel McInerney]

Hi Mortiz,

I looked at i.pr a while ago, but didn't try
the interactive mode for point selection.
If the problem you are encountering persists,
you could digitise a vector map of labeled training
locations, which you could then use in i.pr.training.
This will bypass the need to interactively select training
points when you run the module.


i.pr.training map=`g.mlist type=rast pattern="spot.ms*" sep=","`
training=ipr_training4 vector=YourLabeledVector rows=3 cols=3
vis_map=spot.comp

Hope this helps. Would be interested in hearing how
you get on.

Regards,
Daniel.
