<｜begin▁of▁sentence｜>### Instruction:
Given the neural network graph of the C. elegans, which can be read from a GML file named celegansneural.gml, can you use the mod_r community detection algorithm in cdlib to perform local community detection for a specific node? And can you output the community structure in JSON format?
### Response:
import networkx as nx
from cdlib import algorithms

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

# Perform local community detection using mod_r algorithm with a specified node
node_id = 1 # replace with an actual node id from the graph
local_community = algorithms.mod_r(G, node_id)

# Convert the community structure to a JSON object
local_community_json = local_community.to_json()
print(local_community_json)
