**Purpose**

**Trycycler consensus** generate a consensus contig sequence for each cluster. It does this by converting the MSA into a graph form. When there is a tie between options, Trycycler aligns the reads to the alternative sequences and chooses the option with the best read alignment scores.

    ::

        GGAGGAGCTTTT-CGCCGCAGTCAACGAA-TAGCGTCTGAAAACGTGTATCAT
        GGAGGAGCTTTTTCGCCGCAGTCAAC--A-TAGCGTCTGAAAACGTGTATCAT
        GGAGGAGCTTTTTCGCCGCAGTCAAC--ATTAGCGTCTGAAAACGTGTATCAT
        GGAGGAGCTTTTTCGCCGCAGTCAAC--A-TAGCGTCTGAAAACGTGTATCAT
        GGAGGAGCTTTT-CGCCGCAGTCAAC--A-TAGCGTCTGAAAACGTGTATCAT

From the hypothetical MSA, Trycycler generates a variation graph:

    ::

                     ↗ - ↘               ↗ GAA- ↘
                     ↗ T ↘               ↗ --A- ↘
        GGAGGAGCTTTT → T → CGCCGCAGTCAAC → --AT → TAGCGTCTGAAAACGTGTATCAT
                     ↘ T ↗               ↘ --A- ↗
                     ↘ - ↗               ↘ --A- ↗



The first thing Trycycler uses to choose variants is minimum total Hamming distance to the other variants. In cases of a minimum total Hamming distance tie, Trycycler will align the reads to each possibility and choose the option with the highest total read alignment score. Read alignment scores are calculated using a simple scheme: match score = 1, mismatch penalty = 1, gap open/extension penalty = 1.
