Using the Python code

In this section, we are going to use the similarity join code we have developed to start joining iSAX indexes. The source code of join.py is presented in three parts. The first part is the following:

#!/usr/bin/env python3
from isax import variables
from isax import isax
from isax import tools
from isax.sax import normalize
from isax.iSAXjoin import Join
import sys
import pandas as pd
import time
import argparse
def buildISAX(file, windowSize):
    variables.overflow = 0
    # Read Sequence as Pandas
    ts = pd.read_csv(file, names=['values'],
        compression='gzip', header = None)
    ts_numpy = ts.to_numpy()
    length = len(ts_numpy)
    ISAX = isax.iSAX()
    ISAX.length = length
    for i in range(length - windowSize + 1):
