Sorry to have been unclear. It seems that the new "boundary" pixels are created at the what seems to be edge of the input map's regional extents. To clarify, there is no "boundary of pixels" (eg. "frame") in the original raster stream seg maps produced by r.watershed, but r.proj creates a one to two pixel wide "frame" that outlines the reprojected maps. to repeat, there is NO boundary in the origianl maps, but there IS a boundary after reprojection. Why is this happening?<br>

</div>What do you mean by "the original map's boundary"?<br>
<br>
If the source map has a border embedded in its data, it will get<br>
re-projected along with the rest of the map.<br>
