[Qgis-user] problems making grass training map via qgis

[Samantha Goodchild-Brown]

Can anyone tell me how to make a training map for supervised 
classification using QGIS Grass (1.8).

I have successfully made the polygons with label attributes (as a grass 
vector layer - attribute table now looks the same as the sample datasets 
from installation) but these attributes are lost when converting to 
raster. Hence my raster comes out as one cell (one value to region extents).

If I use Grass GUI (6.4.2) to convert a vector polygon to a raster, 
georeferencing gets lost.

Are these known bugs? can someone give me a workaround? Or fix my 
methodology if I am making common dingbat errors.

Thanks
Sam
