What
can I do with ClustalW?
The program ClustalW can be used for two purposes:
1. It can be used to produce a multiple sequence alignment. Using the web form the user need only
input or upload a file of the sequences that they want to align in an accepted
format. The other options on the form are set to the default values for
producing a multiple alignment. The user can use the defaults or they can make
some changes on the form to customise their run. A multiple sequence alignment
of the sequences submitted will be returned to the user (.aln file).
2. It can be used to produce a true phylogenetic tree. In order to use this option, the user must
input or upload a multiple alignment of sequences in one of the standard
multiple alignment formats (.aln file). Then, in the phylogentic tree section
of the form, they must choose one of the tree type options; NJ, Pyhlip or Dist.
These are programs for drawing phylogenetic trees. This time the user will
retrieve a .ph (always), .dst and/or .nj files (depending on options chosen),
which will contain the phylogenetic trees.
By default, the form is set to produce a multiple
alignment.
