  The analysis pipeline comprises the following steps:
  -1. Alignment: Sequences are aligned to the reference genome using our custom Nextalign alignment algorithm.
  +1. Sequence alignment: Sequences are aligned to the reference genome using our custom Nextalign alignment algorithm.
  2. Translation: Nucleotide sequences are translated into amino acid sequences.
  3. Mutation calling: Nucleotide and amino acid changes are identified
  -4. PCR primer changes are computed
  -5. Phylogenetic placement: Sequences are placed on a reference tree, clades assigned to nearest neighbour, private mutations analyzed.
  -6. Quality control: Quality control metrics are calculated
