# fn() tripletLibraryExtension
Performs a full or group-based consistency extension.

Defined in | <seqan/graph_msa.h>
Signature | `void tripletLibraryExtension(graph[, guideTree, minMembers]);`

## Parameters

`graph` | An AlignmentGraph.
`guideTree` | The guide tree to use.
`minMembers` | Minimum number of sequences per group. If a guide tree and a minimum number of members if given then the triplet extension is limited to groups of sequences.

## Detailed Description

The running time is quadratic in the number of pairwise edges.
