[GRASS-user] GRASS rasterformat supported by GDAL

Greetings

As far as I know GDAL supports GRASS raster format. So, I wanted to get some information regarding a specific Raster using GDALINFO so I decided to test it with nc_spm_08/landsat dataset. But I really don’t know in which sub-folder I shoudl run gdalinfo lsat7_2000_10 file.
And another thing: I’m testing another tool that, it supposes to support GRASS but I need to send them a sample of GRASS raster file. Which file, from which sub-folder, I should send to them?
Thanks
Franz
