<｜begin▁of▁sentence｜>### Instruction:
Given the American College football network graph which you can read from a GML file named football.gml, can you use the modularity maximization (mod_m) function in cdlib to perform community detection starting from a specific node (e.g., node with ID 0)? After community detection, can you convert the community structure into a JSON format and print it?
### 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)
