• This plugin using fiona, shapely, gdal, pysal and Rtree libraries.
• Rtree must be version 0.8.3 or above.
• Pysal must be version 1.14.4 or below. (python -m pip install pysal==1.14.3 --user)
• To install python packages, please using pip or easy_install in OSGEO4W shell.
• Using requirements.txt install file: sudo -H python -m pip install -r requirements.txt
• Step by step installation:

• You can also run the classification from OSGeo4W command shell.
  
  Usage: 
  python  class_achor.py  [class_num]  [sweep_interval]  [field_name]  [shapefile]  [method]
  

  [Method]:
  1:  Localextremes (max and min)
  2:  Localmax
  3:  Localmin
  4:  Hotspot and coldspot
  5:  Neighbors
  6:  Clusters
  7:  Global extremes
  8:  Nested pattern

  for example:
  python  class_achor.py  10  0.2  SUMME  Hamburg.shp  -m  1
