• Align against Greengenes (16S): Use this tool for aligning your set of 16S rRNA gene sequences using NAST or for finding near-neighbors or both. Each query sequence in your uploaded file will be searched for 16S rRNA gene sequences and aligned according to a Core Set of alignment templates. You can even upload a whole fasta genome and NAST will find, extract, and align the 16S rRNA genes for you. Additionally, Simrank (an N-mer comparison tool) will be used to find nearest-neighbors (non-chimeric) as well as nearest-isolates for each of your sequences from the entire Greengenes database...
• Arlequin 3.0: The goal of Arlequin is to provide the average user in population genetics with quite a large set of basic methods and statistical tests, in order to extract information on genetic and demographic features of a collection of population samples. The graphical interface is designed to allow users to rapidly select the different analyses they want to perform on their data. We felt important to be able to explore the data, to analyze several times the same data set from different perspectives, with different selected options. The statistical tests implemented in Arlequin have been chosen such as to minimize hidden assumptions and to be as powerful as possible. Thus, they often take the form of either permutation tests or exact tests, with some exceptions. Finally, we wanted Arlequin to be able to handle genetic data under many different forms, and to try to carry out the same types of analyses irrespective of the format of the data.
