No, you do not need SAGA to run GRASS. You just need it to load the model that uses SAGA (it is included as an example in SEXTANTE, but you can ignore it)
If you go to the SEXTANTE configuration dialog, you will see a "GRASS" entry, and there is an option to enable console output logging. Enable it, run your GRASS command again...and hopefully you will have information about what is happening Regards Victor 2012/12/11 Nick Hopton <nhop...@gmail.com>: > Victor Olaya-3 wrote >> That message is not the problem with the buffer, it is another >> problem.
