[GRASSLIST:781] slope map

[Ramin Safa]

hi
*Regarding slope map(raster),befor v.to.rast my map had a 
  border but after v.to.rast  ..the border is disapeared
and **because of this when i run : r.slop.aspect ....slope
map      
   and aspect map and .. will be wrong, am i right or no?
***if this is true how i save the border and if it is not  

   true how i solve my problem?
****and also if i run v.surf.rst or r.surf contour i have 
   same problem :out of the borderplace(but dont have  
   border) the colors is confused.
actually i think ,in vector map the border is a continuse  
   of end of contours line(related to digitizing)..
Regards
Ramin
