[Qgis-user] HomeRange plugin updated

[John C. Tull]

Here is an error I get now using a shapefile with a set of points  
creating home ranges on field 'ID'. There is only one ID for all the  
points, so it should create a single home range estimate for each  
method.

An error has occured while executing Python code:

Traceback (most recent call last):

HRplugin_dialog.py", line 75, in

mth=mth: self.run(mth))
