#2481: g.gui.iclass: cannot display analysis results because of "No graphics
device selected"
--------------------------------+-------------------------------------------
Reporter: mlennert | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.0.0
Component: wxGUI | Version: svn-trunk
Keywords: g.gui.iclass d.mon | Platform: Unspecified
Cpu: Unspecified |
--------------------------------+-------------------------------------------
Using g.gui.iclass in both trunk and 70release, I do the following:
* load group and subgroup
* load vector training areas
* "Run analysis"
I don't see any of the analysis maps (one per class) in the lower window,
and I get the following error messages:
{{{

}}}
What is really strange is that when I don't load the group and training
areas, but only display an image in the upper or lower display window, I
also get:
{{{
La commande 'd.rast map=pleiades_pan@PERMANENT' a échoué
Détails : No graphics device selected. Use d.mon to select

}}}
but the image is displayed.
Using i.gensig and i.maxlik I can create valid signatures and a
classification.
