What is CHROMA?
CHROMA is a
tool for generating annotated multiple sequence alignments in a
convenient format for publication
What does CHROMA do?
takes your aligned multiple sequence data, annotates residues according
to a consensus and displays the alignment using different font formats
(text and background colours, bold and italic).
The formatted annotation can be sent
directly into Microsoft Word, or saved to a file or Windows Clipboard
in both HTML and "Rich Text" Formats.
output from CHROMA can be edited and ultimately printed out with high
fidelity in other programmes such as Microsoft Word
