I have made a library of peptide mutants using degenerate codons. Mutations have been introduced at 5 positions in the peptide sequence e.g. XXXXXnXXXnXXXnXXXXXnXXXnXXX where X represents the amino acids that were not mutated. I deep sequenced this library and have my FastQ files. Now I would like to see the diversity of amino acids in each mutation site in this library. Is there a way to do this in Bioconductor?
