SNP: standard representation

[francesco.vezzi]

Hi to everybody,
I was wondering about the existence of some standard for representing SNP in a genome. Usually SNPs are codified in a FASTA file simply putting two square brackets around the SNP position (AAACG[T/G]GAT), but obviously this format does not help in having a general view of all the SNP.
Somebody knows some standard format for SNP representation?
The tools for SNP-finding with de novo technologies like MAQ use their own format for SNP representation?

Thanks

For SNP representation in your sequences you might want to use the standard
IUPAC codes, in your case : AAACGKGAT

For a more general description have a look here:

Yes but the this does not help if I have more varieties and I wont to know for every variety what are the SNPs without have to store the entire genome...

Thank anyway
