   2 # pattern_spatial_gen: Initialize spatial dictionary from a SGF collection
   3 #
   4 # We will first gather all spatial features from the SGF collection
   5 # (we take files as arguments) and store these occuring more than 4 times
   6 # in a freshly created spatial dictionary; afterwards, you will probably want
   7 # to do standard pattern-matching.
   8 #
   9 # DO NOT RUN THIS CONCURRENTLY! The dictionary will get corrupted.
  10 #
  11 # To get spatials in competion mode (also get information about unplayed
  12 # spatials present at the board, not just the single played one per move),
  13 # run this script as:
  14 #
  15 #       PATARGS="competition" ./pattern_spatial_gen.sh ...
  16 #
  17 # Similarly, you can set SPATMIN to different number than 4 to include
  18 # spatial features with other number of occurences.
