<｜begin▁of▁sentence｜>### Instruction:
Given the C. elegans neural network Graph which you can read from a gml file named celegansneural.gml, can you use the spectral function in cdlib to perform community detection with a maximum of 2 communities? And can you provide the result in JSON format?
### Response:
from cdlib import algorithms
import networkx as nx

# Read the neural network graph of the C. elegans
G = nx.read_gml('celegansneural.gml')

# Perform Spectral Clustering for Communities Discovery with a maximum of 2 communities
communities = algorithms.spectral(G, kmax=2)

# Convert the community detection result to JSON
result_json = communities.to_json()

print(result_json)
