Description¶

translateDNA translates nucleotide sequences to amino acid sequences.

Usage¶

translateDNA(seq, trim = FALSE)

Arguments¶

seq

vector of strings defining DNA sequence(s) to be converted to translated.

trim

boolean flag to remove 3 nts from both ends of seq (converts IMGT junction to CDR3 region).

Value¶

A vector of translated sequence strings.

Examples¶

# Translate a single sequence
translateDNA("ACTGACTCGA")

[1] "TDS"

# Translate a vector of sequences
translateDNA(ExampleDb$junction[1:3])

[1] "CARVKRRGWRRNSLWFGESTPSDAHRWFDPW" "CARMVILGSCYSRGCGTPGPGDGETQYW"   
[3] "CARVGIDVVVPAAIPGFDYYYGMDVW"     

# Remove the first and last codon from the translation
translateDNA(ExampleDb$junction[1:3], trim=TRUE)

[1] "ARVKRRGWRRNSLWFGESTPSDAHRWFDP" "ARMVILGSCYSRGCGTPGPGDGETQY"   
[3] "ARVGIDVVVPAAIPGFDYYYGMDV"
