Finds Open Reading Frames (ORFs) in each supplied nucleotide sequence, stores found regions as annotations.

Parameters in GUI

ParameterDescriptionDefault value
Annotate as (required)Name of the result annotations.ORF
Search inSpecifies which strands should be searched: direct, complement or both.both strands
Min lengthIgnores ORFs shorter than the specified length.100
Genetic codeSpecifies which genetic code should be used for translating the input nucleotide sequence.The Standard Genetic Code
Require init codonAllows or not ORFs starting with any codon other than terminator.True
Require stop codonIgnores boundary ORFs which last beyound the search region (i.e. have no stop codon within the range).False
Allow alternative codonsAllows ORFs starting with alternative initiation codons, accordingly to the current translation table.False
