Construct phylogenetic tree from SNP data?

[sandesh]

Hello,

I need to construct phylogenetic tree using SNP data.
Lets say, 100 samples with 50 SNPs.
Is there any software?
or any way that I can try.

Thanks for all suggestions

How do you have you SNP data arranged? If it is a multi-FASTA, you should be able to build a tree with most tree building applications. If it's in another format, you'll likely need to get it into multi-FASTA or another sequence alignment format.

It is like this:
L 1 2 3
S1 AA GC TT
S2 TT CC CC
S3 AT GC TC

How can we make multi fasta from this one?
