Parameters are set in the project page. In the CV approach, length K of the oligopeptides or oligonucleotides controls the resolution of the method and is important for getting good results. Our previous studies have shown that better results may be achieved by setting K to 5 for virus (3, 4) , 5 or 6 for prokaryotes (1,7) and 6 or 7 for fungi. Our further study on how to choose K will make the subject of a separate publication. The sequence type (DNA or protein) and email to receive the results are to be entered in the project page. For DNA sequences K may be chosen from 6 to 18 with increment 3. For protein sequences, which are recommended, K = 3-7. If an email is entered, the web page may be safely closed after the project gets running.
