Dear Erik,the consensus module in its current version will not help you. What you have to do is first to compute the profiles for each cluster of sequences in your MSA. Then, you can comput the consensus from that.
Appended is a header with functions to do just that. Code with similar functionality will be part of a future version of SeqAn.
Don't hesitate to send questions, proposals for improvements etc. HTH, Manuel
