Hi,

I have the following error:

Oooops! SEXTANTE could not open the following output layers

Output vector file: /tmp/sextante/otbmeanshiftsegmentationlargescalevectoroutputbdc33d1cf5754b099ae93605846a76e8.shp
The above files could not be opened, which probably indicates that they were not correctly produced by the executed algorithm

Checking the log information might help you see why those layers were not created as expected

when running the following command with the attached image:

sextante.runalg("otb:meanshiftsegmentationlargescalevectoroutput","/home/user/Desktop/NorthCarolina.tif",5,0.1,15,100,100,None,False,True,1,0,"layer",1024,1,0,"",None)

This is the INFO log:

I think it is related to an issue of OTB, about certain projections, described here: https://groups.google.com/forum/?fromgroups#!topic/otb-users/0Te-TnCyVj0 and http://bugs.orfeo-toolbox.org/view.php?id=572

Thank you
