BioSequenceInstances

BioSequenceInstances[bioseq]

expands the possibly degenerate sequence bioseq into all fully specified corresponding sequences.

BioSequenceInstances[bioseq,n]

expands the sequence bioseq into at most n fully specified corresponding sequences.

Details

  • BioSequenceInstances uses the type of the sequence to resolve all degenerate letters into their corresponding fully specified letters.
  • Allowed degenerate letters for DNA and RNA include:
  • BC, G or T/U
    DA, G or T/U
    HA, C or T/U
    KG or T/U
    MA or C
    NA, C, G or T/U
    RA or G
    SC or G
    VA, C or G
    WA or T/U
    YC or T/U
  • Allowed degenerate letters for peptides include:
  • BD or N
    JI or L
    XA, C, D, E, F, G, H, I, K, L, M, N, O, P, Q, R, S, T, U, V, W, Y
    ZE or Q
