I've got a bunch of .ab1 files from sanger sequencing over an exon. Any free programs to quickly find the SNP?

I tried to convert .ab1 to fastq (use Staden package) with the intention to use BWA; but it turns out Staden is an assembly program which gives me one long config from which I cannot call SNP. I guess there could be some commands from Staden that can do the job, but it has a monsterous manual with 700 pages...

So any quick way to call SNP from .ab1 file?

Thanks!

Check out novoSnp

http://www.molgen.ua.ac.be/bioinfo/novosnp/

This program will align your ab1 files on a reference in fasta format and call snps, which you can then validate.

Free for academic use.

There's a linux and windows version.

Indigo (http://www.gear-genomics.com/indigo) calls SNPs and InDels in Sanger Chromatogram files.
