[Qgis-user] NoData on GRASS Raster

[Timmie]

Hello,
I have loaded a GRASS raster directly by opening the mapset.

In GRASS maps itself the NoData, i.e. null(), cells are left transparet.

In QGis these are shown with the colour of the most inferior class.

How can I get them to be transparent?

In the transparency settings (next tab in properties dialogue), only
numerical values are allowed for the NoData field.

A similar dicusssion:

Thanks inadvance for your help,
