Hi Patrick, Please see this page for citation information: http://genome.ucsc.edu/cite.html
There are many ways to calculate a percent difference, and we can't really advise you on what would be the best method for your purposes. However, one quick way would be to use BLAT to map the sequence of your gene to each of the species you wish to compare to: http://genome.ucsc.edu/cgi-bin/hgBlat?command=start On the results page for each BLAT search, you will usually see several hits. There is a percent identity calculated for each hit. Keep in mind that the percent identity only applies to the part of the sequence that aligns, though. This means that a hit that only aligns in a section of 20 base pairs can have a percent identity of 100%, if those 20 bases align perfectly. The score column on the BLAT results page can help you find the best hit. If you have further questions, please contact us again at [email protected]. -- Brooke Rhead UCSC Genome Bioinformatics Group On 2/3/12 8:24 PM, Jeffrey Malone wrote: > I have enjoyed using the website and will be publishing a paper soon > in which I would like to site the page.
