Sorry, this is the expression:
r.mapcalc 'map2=if(map ==1
,if(mode(map[-1,-1],map[-1,0],map[-1,1],map[0,1],map[1,1],map[1,0],map[1,-1],map[0,-1])==1,0,mode(map[-1,-1],map[-1,0],map[-1,1],map[0,1],map[1,1],map[1,0],map[1,-1],map[0,-1]),map))'
Thanks
Luca
seem that much easier will be:
r.neighbors input=your_map method=mode size=3 output=mode_output
r.mapcalc 'first_map=if(your_map==1,output_mode,your_map)'
r.mapclac 'final=if(first_map=1,0,first_map'
