<｜begin▁of▁sentence｜>### Instruction:
Given the Power grid Graph which you can read from a GML file named power.gml, can you use the node perception function in cdlib to perform community detection with a threshold and overlap threshold set to 0.25? Additionally, can you provide a JSON representation of the detected communities?
### Response:
from cdlib import algorithms
import networkx as nx

# Read the power grid graph
G = nx.read_gml('power.gml')

# Apply the Node Perception community detection algorithm with specified thresholds
communities = algorithms.node_perception(G, threshold=0.25, overlap_threshold=0.25)

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