Nucleotide sequences can be entered in FASTA format or plain text.
Sequences in FASTA format or plain text can be pasted in the text box (option A) or uploaded (option B).
Using options A or B, it is possible to analyze up to
500 sequences at a time (character limit: 1,000,000). Example data sets: 75 sequences from Baker (2007) and 151 sequences from Dalai (2009). * For analyzing sequences containing integrase, use the previous version, CPR V. 5.0.
