Note that we only specify the input reference; the tool will name the output appropriately automatically. A sequence in FASTA format begins with a single-line description, followed by lines of sequence data. Converting FASTA sequences . The SeqID identifies the same specimen in all the steps of a submission (for example, in the nucleotide FASTA file, in a protein FASTA file, or in a Source Modifier file). In bioinformatics, FASTA format is a text-based format for representing either nucleotide sequences or peptide sequences, in which nucleotides or amino acids are represented using single-letter codes. In bioinformatics, FASTA format is a text-based format for representing either nucleotide sequences or peptide sequences, in which nucleotides or amino acids are represented using single-letter codes.
