<｜begin▁of▁sentence｜>### Instruction:
As an aerospace engineer, imagine you are tasked with optimizing the flight paths of a fleet of military aircraft. To do this, you will utilize a network graph representation of the relationships between the aircraft and their designated routes. The graph is stored in a GML file called "flight_paths.gml". Your objective is to analyze the community structure within the graph starting from a specific aircraft (e.g., aircraft with ID 0) using modularity maximization. Once the community detection is complete, you must convert the community structure into a JSON format to better understand the relationship between the aircraft and their routes.
### Response:
from cdlib import algorithms
import networkx as nx

# Load the American College football network graph
G = nx.read_gml('football.gml')

# Apply the Modularity Maximization community detection algorithm starting from a specified node
coms = algorithms.mod_m(G, query_node=0)

# Convert the community structure to JSON format
coms_json = coms.to_json()
print(coms_json)
