<｜begin▁of▁sentence｜>### Instruction:
Given the Les Miserables Graph read from a GML file named lesmis.gml, can you use the pycombo function in cdlib to perform community detection? Additionally, could you provide the JSON representation of the resulting NodeClustering object?
### Response:
import networkx as nx
from cdlib import algorithms

# Load a graph
G = nx.read_gml('lesmis.gml')

# Apply Combo for community detection
communities = algorithms.pycombo(G, weight='weight', max_communities=None, modularity_resolution=1.0, num_split_attempts=0, start_separate=False, treat_as_modularity=False, random_seed=42)

# Convert the community structure to JSON
communities_json = communities.to_json()

print(communities_json)
