Perform a multiple sequence alignment using the MAFFT tool (see http://align.bmr.kyushu-u.ac.jp/mafft/software/). The EBI's WSMafft web service (see http://www.ebi.ac.uk/Tools/webservices/services/mafft) is used to access to tool. Note: the WSMafft service used by this workflow is deprecated as of 21st September 2010 and should not be used in any new development. This service is will be retired during 2011. EBI's replacement MAFFT services (REST or SOAP) should be used instead.
