calculates synonymous and non-synonymous substitution rates based on a
set of codon-aligned nucleotide sequences.
Details: Please read the Readme file before using this program!
For alignments smaller than 40 sequences the results will be displayed
on our web site. For larger alignments (more than 40 sequences) you will
receive a job title and reference number and results will be emailed to you.
Alternatively, you can download the Perl version of
SNAP and process your data on your local machine.
Input sequences must be codon-aligned nucleotides. The tool
automatically recognizes several common sequence formats. If your
input format is not accepted, web-based format conversion sites are available.
WARNING: Unaligned sequences or aligned sequences copied from Word (containing non-ASCII characters) may cause
the program to crash or give meaningless output.
