Obtain heterozyous/IUPAC consensus sequences from multiple sequence alignment

Question

[Louis Kok]

Hi all,

I wonder if anyone has tried out something to obtain a consensus sequence with IUPAC code from multiple sequence alignment regardless of the percentage of the bases? For example, at a particular position, there are bases, G and R, which will eventually become a R. For A and T, a W will be the output. Gaps will be ignored for this case.

Appreciate if you could kindly share your idea on doing this.

Thanks a lot
