Using DivideTools

The starting point for analysis is running DivideStability. The other functions in this repository generally require inputs from DivideStability to run.

Errors Relating to GRIDobj Instatances Not Aligning

If you get an error when running AcrossDivide that two GRIDobjs do not align, the most likely cause of this is that you reprojected your DEM before supplying it to DivideStability, but did not specify a cellsize and instead let your GIS program of choice choose a cellsize. This usually results in a cellsize with a long string of decimals that can be rounded differently during different processing steps that can trick TopoToolbox into thinking two GRIDobjs have different dimensions or coordinate systems. To avoid this error, it is strongly recommended that when reprojecting your DEM that you set a cellsize to a whole number. You can do this directly in Matlab using the resample function included with TopoToolbox, for example:

DEM=resample(DEM,round(DEM.cellsize),'bicubic');
