<｜begin▁of▁sentence｜>### Instruction:
Given the Internet graph which you can read from a GML file named as-22july06.gml, can you apply the COAch algorithm with the default parameters to perform community detection? Once the communities are detected, can you generate and print a JSON representation of these communities?
### Response:
import networkx as nx
from cdlib import algorithms

# Read the graph from the file
G = nx.read_gml('as-22july06.gml')

# Apply the COAch algorithm to the graph
coms = algorithms.coach(G, density_threshold=0.7, affinity_threshold=0.225, closeness_threshold=0.5)

# Generate JSON representation of the detected communities
communities_json = coms.to_json()

# Print the JSON object
print(communities_json)
