Hello, when I was executing the command in the command line, I encountered an issue during the final step of converting a TIFF file to a shapefile. I executed the following command: mpiexec -n 8 WaterShedGridToShapefile loganw.tif loganw.shp. However, it was not successful, and it gave an error stating that the file could not be found. I tried looking for the executable file for this command in the folder "C:\Program Files\TauDEM\TauDEM5Exe", but I couldn't find it. Can you please help me resolve this issue? Thank you very much. 微信图片_20231213205436

There is no watershedgridtoshapefile command line executable. Here TauDEM uses a built in ArcGIS function to produce a shapefile from the grid. If you see https://hydrology.usu.edu/taudem/taudem5/help53/WatershedGridToShapefile.html it does not list the mpiexec command as an option, while for other functions (e.g https://hydrology.usu.edu/taudem/taudem5/help53/StreamReachAndWatershed.html) it does.
