Sequences can be in GCG, FASTA, EMBL (Nucleotide only), GenBank, PIR/NBRF, PHYLIP or UniProtKB/Swiss-Prot (Protein only) format. Three or more sequences to be aligned can be entered directly into this box. Note that the parameters are validated prior to launching the tool on the server and in the event of a missing or wrong combination of parameters, the user will be notified directly in the form. Using the submit button will effectively submit the information specified previously in the form to launch the tool on the server

And finally, the last step is always the tool submission step, where the user can specify a title to be associated with the results and an email address for email notification.

In the following steps, the user has the possibility to change the default tool parameters.

The first steps are usually where the user sets the tool input (e.g.

Running a tool from the web form is a simple multiple steps process, starting at the top of the page and following the steps to the bottom.Įach tool has at least 2 steps, but most of them have more:

CLUSTAL W: Improving the sensitivity of progressive multiple sequence alignment through sequence weighting, position-specific gap penalties and weight matrix choice.Web interface for Clustal Omega is available at : How to use the tool Thompson JD, Higgins DG, and Gibson TJ (1994). Multiple sequence alignment with hierarchical clustering. For further details, see the CLUSTALW documentation.Ĭorpet F (1988). Pairwise alignment parameters control the speed and the sensitivity of the initial alignments, whereas multiple alignment parameters control the gaps in the final multiple alignments. The input parameters are classifed into Pairwise and Multiple Alignment Parameters. It takes into account sequence weighting, positions-specific gap penalties and different weight matrix. In the third, the multiple alignment is built using the dendrogram as a guide. Then, in the second, a dendrogram is constructed describing the approximate groupings of the sequences by similarity. In the first one, all sequences are aligned by pair. Sets how the pairwise scores are computedįor further details, see the MultAlin documentation.ĬlustalW is a progressive multiple sequence alignment program (Thompson et al., 1994). Gives all sequences an equal weighting (1.0) Performs the alignment in a single iteration, resulting in a faster computation, but a less accurate alignment Sets end gaps to be penalized the same as internal gaps Sets the penalty to create extensions to the gaps Sets the penalty to create a gap in the alignment Sets the matrix to use for scoring matches in the alignment Selects whether to show the aligned sequences in the input or in the aligned order The parameters and their functions are outlined in the table below: Parameter MULTALIN is a progressive multiple sequence alignment program which allows you to align several biological sequences using hierarchical clustering (Corpet, 1988). The time it takes before your results are returned depends on the speed of your internet connection and the length and number of sequences to be aligned. After adjusting the appropriate parameters, simply push the Submit button to invoke the algorithm. If you have both DNA and protein sequences open, only the sequence type of the currently selected sequence will be used. This will open the appropriate form in the Internet Tool Window. Open your target protein or DNA sequences, then select the desired algorithm under Multiple Alignment from the Internet menu. This section provides an introduction to the interface and a brief overview of the different algorithms.

The processes are performed over the internet on fast servers, which will provide alignment results faster than most local desktop pc alignment tools. Multiple DNA or protein sequences can be aligned from Expression using either the MultAlin or ClustalW algorithms.
