Arguments	Name	Type	Description
	`path`	`PATH`	The path to be sliced.
	`offset`	`INTEGER`	The offset to begin the new path from. The default is: `0`.
	`length`	`INTEGER`	The length of the new path. The default is: `-1`.

Usage Examples

The examples in this section are based on the following sample graph:

MERGE (manUtd:Club {name: 'Man Utd'})
MERGE (juventus:Club {name: 'Juventus'})
MERGE (flamengo:Club {name: 'Flamengo'})

MERGE (premierLeague:League {name: 'Premier League'})
MERGE (serieA:League {name: 'Serie A'})
MERGE (brasileirao:League {name: 'Brasileirão'})

MERGE (england:Country {name: 'England'})
MERGE (brazil:Country {name: 'Brazil'})

MERGE (uefa:Confederation {name: 'UEFA'})

MERGE (manUtd)-[:IN_LEAGUE]->(premierLeague)
MERGE (premierLeague)-[:IN_COUNTRY]->(england)
MERGE (england)-[:IN_CONFEDERATION]->(uefa)

MERGE (juventus)-[:IN_LEAGUE]->(serieA)

MERGE (flamengo)-[:IN_LEAGUE]->(brasileirao)
MERGE (brasileirao)-[:IN_COUNTRY]->(brazil);

The apoc.path.slice function returns a subset of a path starting from a specified offset for a specified number of elements.

The following returns a subset of the combined path, starting from an offset of 1 for a length of 1:

MATCH (club:Club)
OPTIONAL MATCH path1 = (club)-[:IN_LEAGUE]->(league)
OPTIONAL MATCH path2 = (league)-[:IN_COUNTRY]->(country)
WITH apoc.path.combine(path1, path2) AS path
RETURN apoc.path.slice(path, 1, 1);

Results
apoc.path.slice(path, 1, 1)
(:League {name: "Premier League"})-[:IN_COUNTRY]→(:Country {name: "England"})
(:League {name: "Serie A"})
(:League {name: "Brasileirão"})-[:IN_COUNTRY]→(:Country {name: "Brazil"})
