I can succesfully perform SAGA kernel density analysis with Sextante (1.0.7) in QGIS 1.8.0. But i want to built an automated tool for this job with Sextante Modeler. But i got foolish errors. This analysis tools works succesfully directly under Sextante but never works with Modeler. First screen shows kernel density analysis screen that called directly Sextante toolbox...
Here is the another screen capture. Second screen show Modeler inputs and the error. i entered every input and output but everytime i got same error...
Here is the Sextante's configuration file for SAGA Kernel Density Analysis tool. Maybe you find the solution...
Kernel Density Estimation
ParameterSelection|KERNEL|Kernel| quartic kernel;1 gaussian kernel
ParameterSelection|TARGET|Target Grid| user defined
Extent USER_XMIN USER_XMAX USER_YMIN USER_YMAX
NOTES: ###Maybe you will say that QGIS Heatmap tool can handle this. You are correct but i have to build an automated analysis model so i have to work with analysis tools adapted with Sextante Modeler or Sextante Script but i have no idea with scripts... ###I got error with Sextante 1.0.9 but i work succesfully 1.0.7...I need your help, thanks in advance...
