and what is the exact r.width.funct command you used?

see 

https://grass.osgeo.org/grass74/manuals/addons/r.width.funct.html

for an example:

###########
g.region raster=elevation -p

# Calculate flow direction
r.stream.extract elevation=elevation threshold=1000 \
direction=direction 

# Create outlet point 
echo "637304.924954,218617.100523" | v.in.ascii input=- sep=',' out=outlet

# Convert outlet point to raster
v.to.rast input=outlet type=point output=outlet use=cat

# Calculate distance to outlet map
r.stream.distance -o stream_rast=outlet \
direction=direction distance=dist2out

# Calculate width function
r.width.funct map=dist2out image=/tmp/my_basin
###########
