Defined in | seqan/reduced_aminoacid.h
Signature | `typedef Buchfink11 Tag<Buchfink11_>;`

## Detailed Description

This is the 11-character reduction defined by Buchfink et al, 2014, https://www.ncbi.nlm.nih.gov/pubmed/25402007

This alphabet is used by tool Diamond.

Since it was created from the 20-letter alphabet the clusters in SeqAn are not identical (they contain more symbols). This is the clustering:

    'A', // A S T X
      'B', // B D E K N O Q R Z
      'C', // C U
      'F', // F *
      'G', // G
      'H', // H
      'I', // I J L V
      'M', // M
      'P', // P
      'W', // W
      'Y'  // Y
