Hi,

I have a string of letters where certain letters can represent 2 or more options, e.g. if there is an R it means 'substitute either A or G in this position' and an S means 'subsitute either C or G'. So, a string like RAGGTS can be expanded to be:

1.AAGGTC
2.AAGGTG
3.GAGGTC
4.GAGGTG

How can a write some code that will expand the string RAGGTS into these 4 separate sequences and do something like store them in an array?

Thanks! Becky
