== Calculating a Multiple Sequence Alignment ==
BioRuby can be used to execute a variety of multiple sequence alignment
-programs (such as MAFFT, Probcons, ClustalW, Muscle).
-In the following, examples for using the MAFFT and
+programs (such as [http://mafft.cbrc.jp/alignment/software/ MAFFT], Probcons, ClustalW, Muscle).
+In the following, examples for using the MAFFT and Muscle are shown.
