MALIG (Multiple ALIGnment) is a tool which allows you to align many (more than 100) DNA sequences. All you have to do is choose the value of the parameters below this text and upload a file with the sequences in FASTA format. MALIG will return the aligned sequences and a picture of the alignment either to the web browser or to the e-mail direction specified, depending on your choice. A limitation of MALIG is that the original sequences must not be longer than 2000 nucleotides. In fact, sequences shorter than 1800 bases are strongly recommended. For a proper view of the aligment, you must use a fixed size font, such as Courier.

Once all the fields in the form below are filled, press the "Submit Form" button to start the alignment.
