this is what I meant by looping over each subbasin, but that is exactly what I would like to avoid as it would take a lot of time for 1000+ subbasins and I dont really need all the other analysis.
Michel, If you look at the code for that module you'll see that you cannot get directly to the end without calculating all the intermediate values; one attribute builds on those calculated before it. As long as the intermediates are being calculated there's no reason to not put their results in the overall table. If you want only main channel length for 1000+ subbasins you might figure out a way to calculate that directly and modify the code (with a different module name, of course) to do that. This is one of the advantages of open source software licensed under the GPL. Rich -- Richard B. Shepard, Ph.D. | Have knowledge, will travel.
