The name pretty much says it all - my project takes protein sequences and aligns them. It outputs the results graphically for your viewing pleasure. For users who don't have their own protein sequences at hand, I've included a few sample proteins. To use, select a sample protein from the list and then select which species you would like to compare. If you aren't using a fast computer, it may not be a good idea to click "select all" and submit. The other option is to align your own protein sequences. There are online databases from which these could be retrieved, including Entrez Protein. Click here for a list of other databases. Technical info: The program uses the Feng-Doolittle algorithm for multiple alignment, with the UPGMA clustering method as the guide tree. It was written in C. Note: selecting or entering exactly two sequences invokes a separate pairwise alignment program that is faster and more accurate than the multiple alignment program.
