<｜begin▁of▁sentence｜>### Instruction:
Given the Astrophysics collaborations graph which you can read from a GML file named astro-ph.gml, can you use the ASLPAw algorithm in cdlib to detect communities? And can you generate a JSON representation of the detected communities? Notes: You need to print the JSON representation of the communities.
### Response:
import networkx as nx
from cdlib import algorithms

G = nx.read_gml('astro-ph.gml')
coms = algorithms.aslpaw(G)

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