Hi all
Is qgis has a function like "stream link" in Arcgis
which can convert the stream raster to feature.
I tried with raster to vector function in grass and
qgis.
Sorry, this message got messed up - trying again...
Hi Ming,
There is a place where your raster "line" is two pixels wide,
and this is also where the "errors" occurs.
I guess that the raster "line" needs to be properly thinned
(to a one pixel wide skeleton) before running this algorithm.

Hi Ming,
The errors occur where raster "line" is two pixels wide, and
that is also where you find the "errors".
