Combine FASTA converts multiple FASTA sequence records into a single sequence.

Combine FASTA converts multiple FASTA sequence records into a single sequence. Use Combine FASTA, for example, when you wish to determine the codon usage for a collection of sequences using a program that accepts a single sequence as input.

Paste the FASTA sequences into the text area below. Input limit is 500,000,000 characters.
