This tool accepts a group of aligned sequences (in FASTA or GDE format) and calculates the identity and similarity of each sequence pair. Identity and similarity values are often used to assess whether or not two sequences share a common ancestor or function.
Paste the raw sequence or one or more FASTA sequences into the text area below.
Input limit is 100,000 characters.:
Enter the groups of similar amino acids separated by commas to be used for the similarity calculation. If you are comparing DNA sequences, leave this text area empty.
