**Note**

This tool allows you to run a multiple sequence alignment with ClustalW2 (see Clustsrc_) using the default options.
 
For a tutorial introduction, see ClustalW2_

You can align DNA or protein sequences in the input file which should be multiple sequences to be aligned in a fasta file

A log will be output to your history showing the output Clustal would normally write to standard output.

The alignments will appear as a clustal format file or optionally, as phylip or fasta format files in your history. If you choose fasta as 
the output format, you can create a 'Logo' image using the Sequence Logo tool.

If Clustal format is chosen, you have the option of adding basepair counts to the output

A subsequence of the alignment can be output by setting the Output complete parameter to "Partial" and defining the offset and end of the subsequence to be output
