You should see the version number printed without errors.

Quick Test¶

Run a minimal example to ensure all components work:

from LZGraphs import LZGraph

# Create minimal test data
sequences = ['CASSLEPSGGTDTQYF', 'CASSDTSGGTDTQYF']

# Build a graph
graph = LZGraph(sequences, variant='aap')
print(f"Graph has {graph.n_nodes} nodes and {graph.n_edges} edges")
