Ident and Sim

Ident and Sim 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. Since many alignment programs do not calculate these values, you may find Ident and Sim quite useful when making pairwise comparisons.

Paste the aligned sequences in FASTA or GDE format into the text area below.
