====== Script for Processing and Aggregating Track Data to CSV ======

This Python script is designed to traverse a directory structure to find files with a '.track' extension, read their contents using a specialized function (`read_trk`), and aggregate specific information from these files into a single CSV file named 'lastModels.csv'. It specifically extracts the last entry from each track file, adds the model name derived from the file's name, and then compiles these entries into a DataFrame. This aggregated data is then saved in the specified directory. The script also counts and reports the number of track files that were skipped due to size constraints.

<code python>
import os
from pysep.io.trk import read_trk
import pandas as pd
from tqdm import tqdm
import sys
trks = list()
for root, dirs, files in os.walk(sys.argv[1]):
    trkFiles = list(filter(lambda x: x.endswith(".track"), files))
    if trkFiles:
        trkFile = trkFiles[0]
        trks.append(os.path.join(root, trkFile))
temp, meta = read_trk(trks[0])
names = [x for x in temp[0].columns]
names.append("MODELName")
lastModels = pd.DataFrame(columns=names)
skipped = 0
for trk in tqdm(trks):
    modelName = '.'.join(os.path.basename(trk).split('.')[:2])
    if not os.stat(trk).st_size < 1e4:
        trkContnent, metaContnent = read_trk(trk)
        trkContnent = trkContnent[0]
        lastModel = trkContnent.iloc[-1]
        lastModel["MODELName"] = modelName
        lastModels = lastModels.append(lastModel)
    else:
        skipped += 1
lastModels.reset_index().to_csv(os.path.join(sys.argv[1], "lastModels.csv"), index=False)
print(f"Skipped {skipped} track files")
