GeneticCodes is a map holding genetic codes. This file was generated using gcode program from NCBI genetic codes file.

Functions

func GetCodons 

func GetCodons() <-chan string

GetCodons returns a channel with every codon (64).

func Wrap 

func Wrap(seq string, n int) (s string)

Wrap inputs a string and wraps it so string length is n characters or less.

Types

type GeneticCode 

type GeneticCode struct {
	// Id according to NCBI.
	ID int
	// Genetic code name.
	Name string
	// Short name (if present).
	ShortName string
	// Map from codon to amino acid or '*' for stop codon.
	Map map[string]byte
	// NCodon is total number of codons (61 for the standard code).
	NCodon int
	// CodonNum translates codon into its' number.
	CodonNum map[string]byte
	// NumCodon translates codon number to its' string.
	NumCodon map[byte]string
}

GeneticCode is a structure holding genetic code.

func (*GeneticCode) IsStopCodon 

func (gcode *GeneticCode) IsStopCodon(codon string) bool

IsStopCodon tests if the string is a stop-codon (DNA alphabet, capital letters).

func (*GeneticCode) Translate 

func (gcode *GeneticCode) Translate(nseq string) (string, error)

Translate translates nucleotide sequence string into the protein string. Error is returned is sequence is not divisible by three, non-terminal stop-codon is found or wrong codon is encountered.

type Sequence 

type Sequence struct {
	Name     string
	Sequence string
}

Sequence is a type which is intended for storing nucleotide or protein sequence with it's name.

func (Sequence) String 

func (seq Sequence) String() (s string)

String returns a sequence in FASTA format.

type Sequences 

type Sequences []Sequence

Sequences stores multiple sequences. E.g. a sequence alignment.

func ParseFasta 

func ParseFasta(rd io.Reader) (seqs Sequences, err error)

ParseFasta parses FASTA sequences from a reader.

func (Sequences) String 

func (seqs Sequences) String() (s string)

String returns sequences in FASTA format.
