<｜begin▁of▁sentence｜>### Instruction:
As a Ghostwriter for a network analysis company, you have been tasked with utilizing the MCODE function in cdlib to detect communities in the Les Miserables network data stored in a GML file named lesmis.gml. Your next assignment includes providing a JSON representation of the detected communities.
### Response:
import networkx as nx
from cdlib import algorithms

# Load the graph from Les Miserables dataset
G = nx.read_gml('lesmis.gml')

# Apply MCODE algorithm to find communities (protein complexes in this context)
coms = algorithms.mcode(G, weights='weight', weight_threshold=0.5)

# Convert the communities to JSON format
coms_json = coms.to_json()

print(coms_json)
