DEM

Hi GRASS users,
I have imported a DEM file into GRASS, I generated a contour file without any
problem, but when I tried to generate a slope file with GRASS; it generated a
raster file similar to the contour file. Showing lines. The space between
each line? shows no slope (0). Is there any wrong with my file or GRASS is not
interpolating correctly the DEM file.
Thank you in advance.
