Comment(by bhlevca):

 I have a large number of points (~20000) and the script runs fine until it
 reaches the point of summation of cost weights.

 Then Python gives up because there are too many items in the arguments
 list.
 I am wondering if the script could be changed to work around Python's
 limitation

 Here is the error:

 Removing anomalies at site positions ...
 Applying radial decay ...
 Finding sum of squares ...
 Summation of cost weights ...
 ...
 omitted lines
 ...
   File "/usr/lib64/python2.7/subprocess.py", line 1327, in
 _execute_child
     raise child_exception
 OSError: [Errno 7] Argument list too long
