Glossary: Sequence logo

What is a sequence logo?

Sequence logos are created from collections of aligned sequences and consist of stacks of letters representing individual positions in the sequence alignment. The height of each stack indicates the sequence conservation at that position of the alignment measured in bits, and the height of each symbol within the stack reflects its relative frequency at that position.

Sequence logos can be created using sequence logo generators (also known as sequence logo makers). One such tool is Eckher Sequence Logo Maker which is web-based and does not require downloading or installation.
