Hi I'm Michele and this is my first e-mail in this mailing list and I hope to find a little help :-) I'm working to classify some UAV images and I would like to follow the method proposed by Grippa et al. 2016(http://proceedings.utwente.nl/367/1/Grippa-An%20Open-Source%20Semi-Automated%20Processing%20Chain%20For%20Urban%20OBIA%20Classification-28.pdf) working with i.segment.uspo(https://grass.osgeo.org/grass72/manuals/addons/i.segment.uspo.html). So I downloaded and installed the OSGEO Live 9.5 and from GRASS shell I installed i.segment.uspo(https://grass.osgeo.org/grass72/manuals/addons/i.segment.uspo.html) and the required r.neighborhoodmatrix(https://grass.osgeo.org/grass72/manuals/addons/r.neighborhoodmatrix.html). Everything went right but when I try to use i.segment.uspo(https://grass.osgeo.org/grass72/manuals/addons/i.segment.uspo.html) I get an error message because there is something wrong with r.neighborhoodmatrix(https://grass.osgeo.org/grass72/manuals/addons/r.neighborhoodmatrix.html). This is the error message retrieved trying to use r.neighborhoodmatrix(https://grass.osgeo.org/grass72/manuals/addons/r.neighborhoodmatrix.html):
############################# Traceback (most recent call last): File "/home/user/.grass7/addons/scripts/r.neighborhoodmatrix", line 137, in <module> main() File "/home/user/.grass7/addons/scripts/r.neighborhoodmatrix", line 123, in main unique_neighbors_sorted = gscript.natural_sort(unique_neighbors) AttributeError: 'module' object has no attribute 'natural_sort' ############################# I tried to re-install the module but I retrieved the same message. Someone can help me? Thank you Michele
