<｜begin▁of▁sentence｜>### Instruction:
Given the neural network of the Caenorhabditis elegans worm, which you can read from a GML file named celegansneural.gml, can you use the Louvain method in cdlib to perform community detection, and subsequently write the identified community structure to a CSV file and read it back into a NodeClustering object?
### Response:
import networkx as nx
from cdlib import algorithms, readwrite

# Load a graph from a GML file
G = nx.read_gml('celegansneural.gml')

# Perform community detection using the Louvain method
coms = algorithms.louvain(G)

# Write the identified communities to a CSV file
readwrite.write_community_csv(coms, 'communities.csv', ',')

# Read the community structure from the CSV file
coms_from_csv = readwrite.read_community_csv('communities.csv', ',', nodetype=str)
