source
BioSymbols.ACGTN — Constant
ACGTN

Unambiguous DNA and DNA_N.

Examples

julia> ACGTN
(DNA_A, DNA_C, DNA_G, DNA_T, DNA_N)
source
BioSymbols.ACGUN — Constant
ACGUN

Unambiguous RNA and RNA_N.

Examples

julia> ACGUN
(RNA_A, RNA_C, RNA_G, RNA_U, RNA_N)
source
BioSymbols.BioSymbol — Type

The BioSymbol type is an abstract type that represents any kind of biological symbol that may appear in data such as biological sequences, SNP datasets and more.

Every abstract or concrete subtype of BioSymbol is expected to have the following methods defined:

isterm bytemask prefix type_text

source
BioSymbols.alphabet — Method
alphabet(AminoAcid)

Get all symbols of AminoAcid in sorted order.

Examples

julia> alphabet(AminoAcid)
(AA_A, AA_R, AA_N, AA_D, AA_C, AA_Q, AA_E, AA_G, AA_H, AA_I, AA_L, AA_K, AA_M, AA_F, AA_P, AA_S, AA_T, AA_W, AA_Y, AA_V, AA_O, AA_U, AA_B, AA_J, AA_Z, AA_X, AA_Term, AA_Gap)

julia> issorted(alphabet(AminoAcid))
true
source
BioSymbols.alphabet — Method
alphabet(DNA)

Get all symbols of DNA in sorted order.

Examples

julia> alphabet(DNA)
(DNA_Gap, DNA_A, DNA_C, DNA_M, DNA_G, DNA_R, DNA_S, DNA_V, DNA_T, DNA_W, DNA_Y, DNA_H, DNA_K, DNA_D, DNA_B, DNA_N)

julia> issorted(alphabet(DNA))
true
source
BioSymbols.alphabet — Method
alphabet(RNA)

Get all symbols of RNA in sorted order.

Examples

julia> alphabet(RNA)
(RNA_Gap, RNA_A, RNA_C, RNA_M, RNA_G, RNA_R, RNA_S, RNA_V, RNA_U, RNA_W, RNA_Y, RNA_H, RNA_K, RNA_D, RNA_B, RNA_N)

julia> issorted(alphabet(RNA))
true
source
BioSymbols.compatbits — Method
compatbits(aa::AminoAcid)

Return the compatibility bits of aa as UInt32.

Examples

julia> compatbits(AA_A)
0x00000001

julia> compatbits(AA_J)
0x00000600
source
BioSymbols.compatbits — Method
compatbits(nt::NucleicAcid)

Return the compatibility bits of nt as UInt8.

Examples

julia> compatbits(DNA_A)
0x01

julia> compatbits(DNA_C)
0x02

julia> compatbits(DNA_N)
0x0f
source
BioSymbols.complement — Method
complement(nt::NucleicAcid)

Return the complementary nucleotide of nt.

This function returns the union of all possible complementary nucleotides.

Examples

julia> complement(DNA_A)
DNA_T

julia> complement(DNA_N)
DNA_N

julia> complement(RNA_U)
RNA_A
source
BioSymbols.gap — Function
gap(::Type{T})::T

Return the gap (indel) representation of T. By default, gap is defined for DNA, RNA, AminoAcid and Char.

Examples

julia> gap(RNA)
RNA_Gap

julia> gap(Char)
'-': ASCII/Unicode U+002D (category Pd: Punctuation, dash)
source
BioSymbols.iscompatible — Method
iscompatible(x::S, y::S) where S <: BioSymbol

Test if x and y are compatible with each other.

Examples

julia> iscompatible(AA_A, AA_R)
false

julia> iscompatible(AA_A, AA_X)
true

julia> iscompatible(DNA_A, DNA_A)
true

julia> iscompatible(DNA_C, DNA_N)  # DNA_N can be DNA_C
true

julia> iscompatible(DNA_C, DNA_R)  # DNA_R (A or G) cannot be DNA_C
false
source
BioSymbols.stringbyte — Function
stringbyte(::BioSymbol)::UInt8

For biosymbol types that can be represented as ASCII characters, stringbyte(x) returns the printable ASCII byte that represents the character in a string.

Examples

true

julia> stringbyte(AA_Gap) == UInt8('-')
true
