 For the best results, the drainage network should align well with the DEM used. If the network was generated using the DEM, this isn't a problem, but when using external datasets such as NHD, there can be a large spatial disparity between the location of the drainage network in the DEM and in the actual dataset. If this is the case, to the extent possible, the user should edit the network, adjusting it so that it aligns with the network location in the DEM. Additionally, the segment length of the network should be suitable given the DEM resolution. That is, with higher resolution DEMs the network should be segmented at smaller lengths than for coarser DEMs (e.g. 10m). A good length is generally 100-500 times the DEM resolution (e.g. for a 10m DEM, we use 1000m segments, and for a 1m DEM we use 200-500m segments, depending on river size). Stream networks *must contain ONLY SINGLEPART FEATURES. If it contains multipart features*, use a "multipart to singlepart" GIS tool to fix this issue. Finally, to work with the detrending algorithm, network segments *must have 5+ vertices*. Very short, or perfectly straight segments usually don't have enough and the tool will throw an exception, notifying the user of which segments need more vertices.
 
 ## Running the model
-To run the model, go to the releases tab and download the release appropriate for your OS (Windows 64 bit and Linux 64 bit available). Unzip the download folder in a chosen location. For windows, open the folder and double click on the VBET.exe to run the program. For Linux, open a command prompt inside the folder and type the command: ./VBET to run the program.

 In addition to a shapefile of the valley bottom, the tool produces a text file with the same name as the output with "metadata" appended on the end that contains the files and parameter values used for that particular run of the tool.
