About the Multiple Sequence Alignment Viewer

The NCBI Multiple Sequence Alignment Viewer (MSA) is a graphical display for multiple alignments of nucleotide and protein sequences.

To start using Multiple Sequence Alignment viewer go to the Multiple Sequence Alignment Viewer application page.

The application landing page contains links to examples and demo pages that you can study before aligning data on your own.

We also recommend going through the Guide.

The Multiple Sequence Alignment Viewer on the web and NCBI's Genome Workbench are based on the same code libraries and developed by the same team. Researchers looking for more capabilities should check out Genome Workbench.

Feel free to contact us using the feedback link at the top right of the Multiple Sequence Alignment Viewer page. We really appreciate your feedback.

NCBI MSA Viewer uses third party tools and libraries.
